Mark Sturtevant has been kind enough to send the last batch of photos I have, some lovely ones of arthropods. Mark’s captions and IDs are indented, and you can enlarge his photos by clicking on them.
The various arthropods shown here were all photographed from my area in eastern Michigan. Most were taken outdoors where I found them, but a few were staged shots. Let’s begin with spiders.
First up is a species of Hammock Spider, Pityohyphantes sp. These make a small but densely tangled web across leaves and branches in the woods.
Next is an Orchard Orbweaver spider (Leucauge venusta). This is as I found her along a forest trail, but usually they are in their web at an angle where it’s awkward to photograph them. I don’t know what the growths are on the leaf:
The next two pictures are staged focus stacks from the ‘ol dining room table. First is a male Long-jawed Orbweaver (Tetragnatha sp), followed by a slightly older picture of a female for comparison. I favor staged settings for these spiders since they are extremely flighty, and I just don’t have the inclination to lay down in the tick-infested grass near water where they are abundant. What I always say about these very elongate spiders is that their startling appearance is simply because they use their long chelicerae and fangs as delicate chopsticks for handling prey, and they are as harmless to you as a piece of Dandelion fluff. The extra gnarly chelicerae on the male are further modified for mating. During that dangerous time, the pair will grapple face to face with their fangs, and the male uses those upward spurs to hold open the fangs of the female. His very long pedipalps are meanwhile needed to transfer sperm to her genital openings which are waaaay back on her abdomen. This can be seen in the linked picture:
Moving on to insects, next up is an Ichneumon wasp. With the help of iNaturalist, I am inclined to identify this parasitic wasp as Coelichneumon navus:
The common woodland fly in the next picture is possibly a wasp mimic, but it is certainly a predator. It is a species of Robber Fly belonging to the “Laphria canis complex” of very similar species:
The moth shown in the next picture is in the Tiger Moth family (Arctiidae). This is the Isabella Tiger Moth Pyrrharctia isabella, but possibly everyone knows the caterpillar, which is the famous Wooly Bear. The moth came to the porch light one night:
I can’t identify everything, even with the considerable help of AI. All I got for the caterpillar in this picture is that it is some species of “inchworm”, family Geometridae, but I already knew that. The dark puncture mark on the body may mean that it has been parasitized, and if so then it is doomed:
The next picture is a first for me. This is a Pennsylvania Ambush Bug nymph (Phymata pennsylvanica). I have seen high hundreds of adults, which are sit-and-wait predators on flowers and decorated to resemble flower parts. But like my failure to ever see a live Cornish hen (has anyone?), I have never seen a juvenile Ambush bug! I believe that the youngsters stay down low in the foliage:
The insects in the next two pictures are commonly called Red-banded Leafhoppers (Graphocephala coccinea). This species is polymorphic in that some are green and red, and others are a lovely blue and red, as shown with the mating pair. That picture is about 10 years old, but I’ve brought it back for comparison. The picture was taken with my olde camera that had a simple 50mm lens converted to a macro lens with extension tubes. If anyone wants to try out macrophotography, you really don’t need a true macro lens. At least not right away:
The final picture is a species of planthopper that I have not seen for a long time. I call this the “White Derbid”, after its color and its family name Derbidae. The species is Otiocerus coquebertii, and like the other odd -looking members of its family, it may be found by slowly walking along forest trails and peering under the leaves of tree:
