Not sure which species this is but it seems to be different from the T. collinum that I have at my own bee/wasp hotel in Swarthmore, PA. E.g., lacks a large, red, distinct band at waist (see last pic). This pair is at Tyler Arboretum in Media, PA.

I'm wondering whether this might be an Atanycolus. I'm supplying closeups of the antennae in case somebody with better knowledge can confirm presence of notch. Overall visual seems to be a good match but the head shape troubles me a tad.

Found at my bee/wasp hotel. Which is interesting because Atanycolus is parasitic on beetles. I think the beech log I used for homes might have Scolytidae, which I think is a known host for at least one species of Atanycolus. And just in case it was A. cappaerti (yes?) looking for emerald ash borer, we seem to have them in area (here's closest obs on iNaturalist, though not RG: https://www.inaturalist.org/observations/13497661). Sorry for bad image but it spooked pretty quickly.

Thanks for any ID help.

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?

Another paralyzed spider from one of the pairs of Trypoxylon collinum at my bee and wasp hotel. iNaturalist AI suggested Parasteatoda. ??

Not sure whether the spider fell out of the hole or was ejected. The latter scenario, perhaps, might take place when wasps detect a parasitoid egg has been deposited in burrow and they want to start fresh. That's a complete guess but something I've been toying with as I see more spiders at the base of the block the wasps live in.

Actually got to see a bee using the holes in this fence post. I suppose it might be using it for resting, but I hope it is the same type of bee that made the nest. Could it be a male?

The leg spines, eye arrangement, and color say "green lynx spider" to me ... but the abdomen is too spherical. Or do juveniles look that way? Am leaning towards Peucetia longipalpis but according to BugGuide it's not in Pennsylvania. Peucetia viridans is in eastern U.S. (but, again, not in PA at least per BugGuide database of observations).

The spider was likely collected and paralyzed by a Trypoxylon collinum, which occupied a hole several inches above where I found the spider. There is another spider on top left, too.

I'm guessing Photinus pyralis but thanks in advance for correction.

The firefly was methodically exploring nest caps of Chelostoma philadelphi at my bee hotel. Visited perhaps 4 of the nests before I had to leave. I'm guessing it was eating the nectar that the bee uses as plug glue.

This is interesting, and ties in with my June 30 observation https://www.inaturalist.org/observations/13991739 where she's checking out one of the tubes that has a hole in the mud cover. In that observation, I didn't notice it before, but in the lower right side of the photo there's something by the tube. A couple of days ago I noticed something sticking out of the hole in that tube and today finally got around to photographing it. And found more things sticking out of another tube which previously also had a hole in the mud cover. So, it would seem that she is gathering these and poking them in the holes. They look like shed skins to me, but I haven't pulled one out to check - hate to undo her hard work. Has anyone seen this behavior before?

Bees that carve their nests into an old, punky log. They fly too fast in and out to catch in photos well. The last photo shows the 2nd bee pushing sawdust out of the tunnel she is excavating. I caught one, chilled her a little and then took photos and released her back at her home. Saw one bee here last year, with leaves filling the end of the hole, so I suspect this is the same species. I did load the bee photos twice, on purpose, because nobody noticed them at the end of this post and I hoped to get a better ID. I left the bee photos here to show the bee that carver her own nesting holes.

This insect was observed flying around and into the tubes of this mason bee house. Some of the tubes appear to be in use. I've found it difficult to get pictures of the insects I have observed around the mason bee house because the seem to hover briefly, enter the tubes, stay there a while, and leave later.
