Table of Contents

This independent report catalogues the whereabouts and observed condition of all wasp nests I've found in my neighborhood and others nearby.

It is not intended to vilify wasps or any other being. I hope for it to respect, ponder, and share them honestly.

I also wanted to challenge myself to incorporate some of my creative ability on this page, including visual and aural arts like the unfinished song below.
*Throughout this project page, "nest" will refer to the nest of a wasp or bee unless otherwise specified.
*In the content below, elements with red outlines or shadows can be interacted with.
*I captured every non-satellite photo that appears on this page.
*Nature is itself and prone to change--take nothing presented, observed, or pondered here as immutable truth.

Origin

This project owes its existence simply to nature, my own curiosity, and opportunity.

While en route to a class trip around November of 2024, I spied a low-hanging wasp nest and photographed it. Later on, I recalled the handful of them I happened upon in 2022 and 2023. Since I was gifted a superb camera and so often travel with it, I decided to log any other wasp nests that I could find during the colder seasons.

Over the months, I came to realize that this was great timing for such a survey. In Fall and Winter, the wasps are dormant or in hiding, and the nests are much easier to find with many trees bereft of foliage.

I live near an edge of Brooklyn, on a veritable boundary between it and Queens, so it's easy to reach a variety of neighborhoods within but a 45-minute walk.

What are Wasps?

As you may know, wasps are winged insects within the Order Hymenoptera, a classification they share with bees, ants, sawflies, and a few other relatives. Wasps are NOT bees. They do seem to be ancestors from which many bees developed, however. Hornets are specific types of wasps with more robust bodies.

Many people know or revile wasps for their potent bites, venomous stings, or other natural armaments and defenses. Wasps, unlike most bees, are also capable of stinging repeatedly without dying, and some humans are allergic to their venoms. Said stingers are actually modified ovipositors, so males lack them. But some male wasps may have less-threatening defensive spines instead.

There are several subfamilies of wasps, with different social and nesting habits. While humans commonly acknowledge bees for their great work as pollinators, wasps can as well, though perhaps to a lesser degree. Outwardly and behaviorally, wasps are less adapted for the kind of pollination bees can perform superbly. Wasps have fewer hairs than do bees, and lack their pollen-collecting leg "baskets". However, some wasps who pollinate plants specialize, and give their best aid to select plant species. Certain sorts even spend part of their life cycle within fruits.

Some wasps hunt and capture other arthropods to feed to their offspring or set eggs within. In this way, they can be formidable pest countermeasures for agriculturalists if introduced carefully. This means of employing other creatures to help minimize damage to crops, the environment, and human consumers is a part of IPM.

Tools for the Task

Some of the items used in this project--my sketchpad, binoculars, class laptop, camera zoom lens Beyond the computer, data storage, and software used to code this page, I needed my camera, binoculars, and any sort of notepad. The camera (with zoom lens) and binoculars are both great for combing trees and buildings for nests. A cell phone camera may be suitable, too, but you might need to zoom more powerfully than some phones can and use manual controls to retain a clear image.

Identifying Nests

Wasps are diligent builders, although not all chew and collect wood fibers to build the classic, paperlike, aerial nests that you'll find catalogued in my map below. Some instead nest in smaller pot or cannon-shaped cells of mud. Some species may nest underground, within pipes, under the eaves of roofs, and in other places that may bring them close to humans.

During my first job in a video game store, I even once found wasp nest cells inside of a used Nintendo Entertainment System cartridge (which still worked once cleaned!) I wish I had photos of it.

Come the cold seasons, these nests are abandoned. Mated queens, bearing their next generation of eggs, seclude themselves in dormancy. They are often the only survivors. Although wasps remember attractive locations, they don't tend to risk reusing a nest if it endures.

Wasps even perform great home upkeep, not only mending damage, but at times manually heating, aerating, or removing moisture from their dwellings.

I don't disturb active wasp nests, but this project has given me a welcome chance to observe abandoned ones over a frame of several months. Most that I've found have become well-worn, with no one actively repairing them, and a few have fallen and been erased completely by weather. But so many of them endure despite the snow, wind, and rain, and remain recognizeable. This gradual collapse has treated me to some interesting interior views.

A great video of a wasp building a nest can be found here (not my doing.)

Daylight is an important resource in my searches, since other creatures' nests and leavings (including those of humans!) can look similar in the shade or from a distance. Squirrel/bird nests, branch-bound balloons, plastic bags, and even pants have all been distractors. I don't mark an insect nest on my map until I've affirmed that it is one.

Procedure and Tips

My ways of seeking and logging these nests have become more thorough over the months, and may yet improve in similar future efforts. The main aspects of this info collection are
Pathing (determining the routes you scout);
Searching (how you look for these nests);
Logging (how you record your findings.)

The point of proceduralizing this isn't rigidity, but repeatability and data retention! The more reliable your methods, the more chances you'll have for engaging observation. I don't discourage searching or wandering on a whim--it is fun and ofttimes rewarding. With some of the tools mentioned above (or your alternatives,) enough memory for at least 100 photos, and knowledge of the day's forecast, I'd do the following on any outing for this project:

If you use a mapping service, try to choose one that befits the scale of your project and the level of coding ability you're at or want to achieve. I chose ScribbleMaps since it allows custom map markers and map imbedding even with a free account. Had I also taken advantage of Scribble's spreadsheet support, it would have been much easier to track and update my entries. I initially wanted to submit this project once I found 35 nests, but am now beyond four times that. Please consider using a spreadsheet if you expect your map to have over 20 entries, especially if they can change.

Though this project requires no funds, enough money to pay for Scribblemaps' subscription would absolutely improve it. Only then would I have the data storage to give every listing at least one image.

Before learning of Scribblemaps (right or bottom image,) I edited my finds onto Google Maps screenshots (left or top.) I'd have only had ungainly ways to update, combine, and present the data had I continued this way.

Resources and Research

Nest Totals:

Brainstorming This Page

Many draft pages and files went into learning or orchestrating various intriguing layouts, features, and art pieces that I've still failed to complete or incorporate.

generalized plans of markers and elements of this project page My attempts at designing a table you may see below Mock wireframes and element inspirations that are all beyond me Map container or marker ideas, attempting to address readability concerns Drafts and alternate versions of the banner 'image' near the top of this page

The greatest challenge of this project by far has been learning to incorporate an interactive map. I've found over seven dozen nests, and have multiple pictures of each, so I also needed to consider ways to make that load less taxing on a viewer's device. I considered using html map elements to create a map, but with so many areas to define, and hundreds of images to apply for the nests, it could be impractical.

A lesser yet tall impediment was the loss of my camera, which suffered terminal moisture damage when I took it outside briefly during light snow early in December. That rendered me unable to take fine quality photos for a month.

Back in November, I didn't think the project would reach this total or scale. My older photos for this plan weren't labeled or documented as well.

I also want this project to feature original artwork of my own creation, which is difficult since I seldom finish any of my art. I forayed into the use of Piskel, a free, browser-based pixel art application, to create the icons for my map.
Similarly, I learned use of MuseScore 4, to give myself of means applying music I created to this page. My original way of composing music is much more convenient and still my preference, but doesn't let me share files as easily or completely.

Near the end of February, when I finally decided to create a free Scribblemaps account, I had to restart my map since it wasn't preserved in my history. Thankfully, I had many screenshots and a few logs.

The survey and photography were simple and fun, but as anything, can be improved. For example, if I wanted to make this info more exhaustive, I could give each nest a designation and update its info box with a new picture every time I see it. That would allow onlookers to see its deterioration (or repair!) progressively. I could also use my voice recorder to take such notes efficiently. Handling a notepad and repeatedly swapping camera lenses is at times inconvenient.

Also, taking pictures of wasp nests on a home can make the human tenants suspicious. Thankfully, many are but curious, understanding, and ultimately supportive. But I've come to always have this page or my map open on my cell phone to help explain myself. Perhaps a customized shirt, hat, or wearable sign could help ease others.

Research revealed that there are several ways to code and feature interactive maps, though some are beyond my present ability. No matter, developer tools and general curiosity can teach well.
This list on Shorthand.com presents several interactive mapping services, some of which have free versions. Minerva's Owls, the website of an art collection I adore, has an interactive map with the features mine should strive for. Its clean and readable map markers are especially fun.
Google Maps also offers interactive map APIs, which look to be tutorialized well.

Before I present the map, you may want to know what each of its terms and markers mean.
Nest condition will be given as intact, damaged, destroyed, or fallen.

Intact

Damaged

Destroyed

Fallen

This nest is in fine condition. Surpsingly many have remained this way. This nest may have some peeling or torn walls, but remains whole overall. Interior cells may be exposed. Nature has likely worn this nest to shambles. It still hangs, but as just a few exposed cells. Alternately, it may have belonged to a small group that had to abandon it prematurely. Some wasp species normally build small, open nests like this, so there's also a chance it was always this way. This nest has fallen from its host branch or structure. It'll likely be erased after a few more days of weathering. You may no longer be able to find it. This also describes nests that were removed from a building by human means.

How to Use This Map

My custom markers are yet incomplete, so I have to use Scribble's for now. Reddish markers indicate nests found on or after May 1, 2025. Green markers represent those added between February 21, 2025 to April 30, 2025. Blue markers are the oldest--those found between November, 2024 and late February, 2025. A marker that's tipped over horizontally denotes a fallen nest.

You can click on a marker to see more details about its nest, though I still have to fill a few in. Any highlighted perimeter has a summary you can access the same way. Again, a free ScribbleMaps account doesn't offer enough memory for me to post photos of every entry as I want to. You can use the settings in the lower-left corner to allow markers to cluster, then zoom out to see my present total.

I'd like for my custom markers to not only communicate the condition of a nest at glance, but whether it's on a tree or in a building.

I live on the edge of East New York, and regularly transit several bordering areas throughout my common doings. I visited Fulton Park twice, and was excited to find several wasp homes there. If I renew this project next year, I'll be sure to roam a few new areas that I can comfortably access.

Between late October and the date I first wanted to submit this page in March, I found over 80 hymenopterid nests. The greatest counts of nests on single block back then (10 and 8, respectively) were on a large block with ample grass, and the block of a community farm I live near. Unsurprisingly, they seem to be most concentrated around large parks and gardens. There looks to be some variety in nest construction, likely the consequence of different species or available materials. Perhaps especially versed or knowledgeable observers could surmise which materials they used by nest color.

For every nest I found, there are undoubtedly many that I did not or cannot, and more possibly lost to conditions before my search.

Observations and Curiosity

Notable Areas

Richmond St and Chestnut St, near Highland Place.
Hotspot around Richmond and Ridgewood, with a high density of nests.
A neighborhood I wandered mid-May. It's replete with nests, many of which may be newly-built.
76th-78th St, along 101st Ave.
High-density wasp nest site along 101st, near Liberty Ave.
This neighborhood is near Liberty Avenue and "City Line," a long street that abounds with stores. Most of these homes have gardens, and there are some large parks nearby.
Cypress Hills Park
Cypress Hills Park, a large block with fewer nests than I expected.
A park on a large block, with surprisingly few nests. But during the first few months of my survey, it had the most nests by merit of its size alone.
Pink Houses Community Farm
Our community farm had a wasp nest near each corner.
Quite close to where I live, this block had a notable count of nests, with four virtually bordering the community farm itself.
My neighborhood
A broader view of my neighborhood and its mapped nests
Despite my proximity to this area and how often I travel it, several nests here went unnoticed for months. This project even gave me reason to explore some blocks and areas of housing that I never have.

Appealing Finds

Near March's end, I chanced upon a pair of woodpeckers eating from an abandoned wasp nest. That's fine demonstration of an ecological role wasps serve.

I've had the opportunity to see and analyze a few nests after they fell, and was even able to collect the nest shown below for some photos. I especially appreciated a close view of the support columns that the wasps use to secure extra "floors" of their home. There are even a few unfortunate adults left behind.

I've known subways and modern buildings to employ bird-deterrent spikes to try to discourage their habitation. While I've seen or read of various attempts at wasp misdirection, like artificial nests or painting walls to look like the sky, I don't know how well any work. As the climate shifts, these insects may become increasingly prominent neighbors to humans. Perhaps that can be mindfully coordinated to help protect attractive crops that they and other beings mutually enjoy.
As with many living things, there still exist techniques or traits of wasps that humans can productively emulate. The kinematics of insect flight readily inspire miniature flying machines, and their nest architecture could yield space-efficient storage or housing features.
Other possible muses include their ways of communicating and navigating (though perhaps not as well-reported or sophisticated as those of bees); their ways of processing and waterproofing material; and the stinger's similar function to syringes.

In fact, I wonder if containers like these were partly derived from hexagonal nest cells.

This project was a great delight, and gave me a new way to enjoy the outdoors during a season when some of my favorite activities aren't available. It was a joy to exercise my observation, curiosity, and photo skills, and watching the nests endure or change over time was insightful. I'll be able to document or organize any similar future endeavors better, too.

Voices of the Public

Onlookers have treated me to a variety of responses, from puzzled gazes, to concern, to amusement. Many have kindly expressed their wishes for me to see this project through or make something further of it. Some interactions are paraphrased below.

Sydul, a local librarian, during the early months of this task:

"You found that many so far? I wish they were bees instead."

Artise, one of my closest friends, upon being told about this project:

"Yeah, I'm not a fan of wasps... I had to fight some not too long ago."

A friendly stranger who was curious about my photography and learned of my project:

"Interesting! I wish you the best. Are you sure this shouldn't be about bees, though? We're losing them!"

I've made two attempts to report potentially inconvenient nests on a home to their human tenants so far:

On 3/29/25, I tried to contact the inhabitants of 54 Euclid Ave when I found a nest. Though no tenant answered, a neighbor who was sweeping the sidewalk did. He offered to tell them, and also took interest in my project, wondering if it was my profession. He hadn't noticed the nest before our meeting, and asserted that he's originally from Arizona, where he never saw some of the insect species common here in NY.

A woman living at 137-33 79th St had known of the nest(s) above her window for years. The insects have never caused trouble, so she doesn't mind it, and respectfully acknowledges that they must have chosen that spot for a reason. Most of these nests see use for just one active year, so I wonder if it's still in use, and by what.

On 4/20/25, while I walked past a home, a neighbor asked what I was doing. He called my attention to the outline of a nest removed from his neighbor's house, and shared that she had to pay several hundred dollars for that service. Easily missed remnants of a nest that was expensive to remove

Wasps look to have a well-established population in this state, and will likely continue to. But what variety of species do we share these neighborhoods with, and how have their numbers been changing? I hope that ours aren't a grievous hazard to other pollinators, but their presence could well harmonize with indoor or hydroponics farmers looking for some crop protectors. This is, of course, a huge generalization. Their diets and the long-term effects of their presence and "employment" mightn't be so predictable. I hope this project will draw some interest in wasps and their potential effects on the region without purely inciting an aversion to them. I'd love for this effort to prove useful for some nearby ecologists or other scientists/enthusiasts. Perhaps there's some correlation between wasp density and the introduction or spread of other local lifeforms or factors. Human homes are clearly secure structures for these hymenopterids, and they can make use of building surfaces in ways humans can't (even when undesired.)

During one of my class trips in Change-Food-For-Good's Intro to AgTech course, I briefly glimpsed a captivating structure in the distance. A guide told me that it's the Pollinators' Pavillion, a structure made to foster and observe various solitary bee species, though it wasn't presently in service. Could agriculturalists use similar, smaller-scale structures to peaceably invite wasps?

Might any of New York's local wasps be safe biocontrol agents against the spotted lanternflies that presently imperil select state crops? I'm unsure that any of our native wasps could comfortably make meal of adult lanternflies, but they don't reach that state until mid-Summer. That's a while after most of the wasp queens emerge to begin their new nests.

A Smattering of Sources

Four of the books I used to build skill for this project.

Having done this, I'm excited to try to incorporate Kindwise's insect and mushroom identifiers into this site next. I'd like to learn if it can hypothesize wasp species by nests. I relayed a few messages with some company staff, and learned that the identifier was trained with some images of wasps on nests. Still, it isn't expected to be able to gauge species by such a sight alone.

I may also present this to any curious botanists or ecologists, who may be able to descry some correlation between the types of plants in an area and its wasp population.

I'm likely to repeat this project next year, from a fresh count, and hopefully with better methods, coding, camera skill, and accessories.

I want to complete all of my unfinished art on or mentioned on this page, or fashion better alternatives. That means the banner image, music, and custom map markers.

Have you ways to bolster this project?
