Wasp Watching

The past year turned out to be a good one for getting wasp photos for me, particularly this past August. When the first of the goldenrod started to bloom these plants turned into magnets for pollinators of all sorts, but I particularly noticed a lot of wasps, not just in numbers of individuals, but in diversity of species as well.

Before that, wasps had been congregating on the spotted horse mint / spotted bee balm (both common names for monarda punctata) in the pollinator garden by the house. I was having fun seeing how many different kinds I could spot as well as just appreciating their many different shapes and colors… but as I realized going through them later, even some very similar looking ones turned out to be different species.

I wanted to show off in this post some of the wasp variety I’ve been able to photograph through the years, though of course what I’ve managed to photograph is just a tiny sampling of what exists (there are some truly wild looking wasps out there, of which I’ve managed to photograph only a few). Also some of these photos are ones I’m more satisfied with than others.

The northern paper wasp (polistes fuscatus) has a significant amount of variety packed into one species. Their varied colors and markings make them fun subjects, plus I was starting to notice what seemed to be the same individuals hanging out on the same flower patches each day when I was doing really regular wasp walks.

This one was especially colorful.

This is a type of oak gall wasp laying eggs in an oak bud. Oaks are hosts to an impressive number of gall wasps, as well as other gall making insects which is part of why oaks are considered such important members of their ecosystems.

The common name of this wasp is the gold-marked thread-waisted wasp (which sounds more like a description of the wasp than a name… but at least it’s an accurate description!) These are certainly interesting looking creatures, but I’m not particularly happy with most of the pictures of them I have so far. Fortunately they don’t seem to be a rare species so hopefully I’ll be able to get some better pictures at some point.

This tachytes wasp (a genus known as sand-loving or green-eyed wasps) was quite mesmerizing, with both the green eyes and silvery stripes on the wasp’s abdomen being very shiny and reflective. The stripes even seemed to change color depending on the angle and lighting. These were also fast moving wasps, which probably exaggerated the reflective characteristics and made the wasp seem to shimmer in the sun. It also made it that much trickier to get good photos…

The four-toothed mason wasp is a fairly common species, and I’ve photographed them before, but this particular little guy gave me the opportunity to get the best pictures I have of this species.
The same wasp (I have quite a few pictures of him).

This wasp was so tiny you might assume it’s a fruit fly if you see one… and this isn’t even as tiny as wasps get!

This mason wasp (euodynerus crypticus) may not have a common name, and there doesn’t seem to be much information about them out there. What little I was able to find piqued my interest, though; apparently it may be a social wasp, which I hadn’t heard of in the mason wasp family before. In any case, this species was regularly visiting the spotted bee balm, so I got to see them regularly for a little while.
Some sort of ichneumon wasp on the back of my hand. I found this wasp halfway through December!

Many species of solitary wasps, like this rusty spider wasp, specialize in hunting a specific type of prey that they will cache in a nest for their offspring. In the case of spider wasps, they specialize (as their name implies) in hunting spiders. I noticed one of these wasps hanging around the entrance to the garage one day, and then she disappeared into the garage for a while and I lost track of her, only to later spot her dragging a huge spider out!

Myzinum maculatum is another wasp that doesn’t seem to have a common name, but they are closely related to the other thynnid wasps in this post.
Common thread-waisted wasp. I think this wasp had an injured wing, sadly.

I found this cuckoo wasp at a local park. When I’ve seen cuckoo wasps before they’ve been pretty skittish, so I was happy to finally find one that was cooperative!
This picture shows the cuckoo wasp (the same one from the previous picture) between my knuckles, which shows how small this one was.

I’m looking forward to seeing what kinds of wasps I can find this year!
