Crossocerus? I have at least four pics of this little wasp. I think it bears some resemblance to @heatherholm's nesting Crossocerus, but of course I could be mistaken. It does not appear to have pale rings on the top of the tibiae, though:

Heads up @neilvinson @laura_clarke @sinclvan6
This cool little cuckoo wasp was found in the pollinator garden during the 2021 BioBlitz. As far as I can tell, this critter is completely new for Eastern North America on iNat and Bug Guide. I will check with @matthias22 and @johnklymko whether there are any known records for this Genus in the region.

On Salix blossoms at the margin of a sand prairie pocket marsh. This is a bold suggested ID, but it really seems a good match to me, and those wings are unusual. Not too far from the size of a typical house fly, the head looks tachinid, but the rest of the fly less typically so. If this ID is correct, it's a male, the females don't have patterned wings. The four photos are a single individual.

In mostly bare sand on a small dune in a sand prairie -- a small spider wasp probing into the sand. I think its an Anoplius based on the blue-black color, the partial orange abdomen and the leg spines, but I could be wrong. Photos are a series of a single wasp.

On Cicuta maculata blossoms on the border of a prairie pothole marsh. A breeding pair perhaps, they rubbed their antennae quite rapidly. A few minutes later I observed what appeared to be the same species of wasp lurking at the openings of the dens of larger wasps on a nearby sand dune -- maybe 200 meters away. [see" https://www.inaturalist.org/observations/28811923] If I understand the descriptions, these may be from genus Zanysson.

Cuckoo wasp stalking a Trypoxylon collinum nest. It wasn't successful on this occasion (male T. collinum eventually came out of tube and attacked it) but I saw it enter the nest a day later when the male was briefly out.
I don't have a good shot of distal part of abdomen, unfortunately. Caenochrysis? Chrysis?

屬 Oxybelus觀察者
martinlucas描述
On Asclepias amplexicaulis in a sand prairie and old field. Quite a small insect - note the red tegula and black wings - though it seemed a good fit for genus Oxybelus, I didn't find any that have a red tegula and black wings. Please don't rely on this suggested ID until confirmed or corrected by an expert. The two photos depict the same individual - unfortunately I didn't get a photo of the face, this insect was so small it was near the limits of my capacity to capture it.

切葉蜂屬 (屬 Megachile)觀察者
martinlucas描述
My sister Donna https://www.inaturalist.org/people/donnalucas discovered a Megachile nest while digging in her garden, and successfully placed it in a jar for examination. The bees started emerging at about 8:00 am on August 22, 2018. She brought the nest over to my house nearby, and we took it out onto the patio where I photographed the bees emerging, and then flying away. These are rather small Megachile bees -- the nest was found in a suburban looking area of a small town. Remnants of sand prairies and black oak savannas in more or less degraded condition are present nearby. Though I didn't notice it at the time, a green fly also emerged; likely a parasite of these bees. Because I didn't notice the fly at the time, I didn't get good photos, but will nevertheless post them as my next observation (see: https://www.inaturalist.org/observations/18841697). This is a long series posted in chronological sequence, but I hope worth it to some; I have quite a few more but I think these show most of the interesting behaviors. I think at least three bees emerged, but no photo shows more than two. The vessel is a small Pyrex measuring cup.

On an aster (Symphyotrichum) in a sand prairie marsh and thicket area. The predominance of dark markings caught my eye. The flower is most likely Symphyotrichum pilosum, but Symphyotrichum ericoides is similar. This tentative ID is based primarily on the markings but I didn't see a really clear explanation of how to get yellowjackets to species so please don't rely on this until confirmed or corrected by an expert. Photos depict a single individual.

On a sunflower, probably Helianthus X cinereus, in a sand prairie near a marsh. These large Megachile bees were active and rather tame, and lighting conditions were good so I was fortunate to get quite a few good shots; the photos depict more than one individual. Helianthus X cinereus is not available as a choice on iNat so I've simply tagges as "Helianthus". I had formerly thought these were H. hirsutus, though they didn't key out all that well; in summer 2017 Laura Rericha, co-author of "Flora of the Chicago Region" informed me these are X cinereus, perhaps a hybrid of H. mollis and H. occidentalis, both of which are common nearby. Whatever you call them, they seem to be especially attractive to M. fortis. [see also: https://www.inaturalist.org/observations/19800354]

On Monarda punctata in my mostly native sand prairie garden. Based on prior IDs from the site, I'm inclined to think it's Tachytes guatemalensis. The white substance on the top side of its thorax is M. punctata pollen I think; the second photograph illustrates the wasp oriented pollination scheme of this plant. These two photos depict a single individual.

In a fishless, sand bottomed pond with clear, clean water. ID using: http://fwf.ag.utk.edu/mgray/wfs493/HovermanLarvaeID.pdf - Also, the only species of salamander that has been seen in adult form in the area. However, I didn't see the blue-spotted salamander in the key and the habitat for that species is potentially available. Photos are probably not of the same individual. In the third photo, the salamander tries unsuccessfully to eat a large wormlike creature, possible some kind of leech.

屬 Myzinum觀察者
martinlucas描述
A series of photos of an individual female Myzinum wasp visiting Asclepias verticillata on a sand prairie and old field area. This seemed a rather large Myzinum to me. The dotted terga suggest M. carolinianum or obscurum. I see that obscurum is identified by striations on the propodeum. I feel like these may be visible here, but am not sure.
