Released all adult beetles several days back

The rotten wood is doing that thing again where it gets all moldy and gross and it was stressing them out to the point they weren't sleeping, and I didn't have the energy to deal with it. Based on my observations I'm pretty sure the Megapenthes would've been pretty stressed during its waking hours even in a clean enclosure though, as even after I moved it to a clean container full of garden soil (which itself it kept spreading its elytra like it wanted to fly (but never flew; perhaps room temps too cold to flap wings)?

Anyways, guess I'll have to concentrate on sucking hoppers and plants for now. I still have 1 vial of rotten wood that never went bad and still smells nice though and I'm hoping that I can make more of whatever saproxylic microbes are responsible for the smell and mold suppression so I can inoculate other rotten-wood-making containers with them.

Well actually some of the E. lecontei larva vials are also clean-smelling, I lied.

I ignored Easter to catch beetles and emit depression

Caught these two, will attempt to breed. Of note is that Megapenthes contains at least one species of conservation concern in Europe.

Update: Stenochidus is being difficult, it's panicking and behaving abnormally because it's in an enclosed space, will probably release once I have the time. I figured this would happen given that it seems to happen to a lot of small flying plant-dwelling beetles but wanted to test. Put it on a potted plant in the meantime to soothe it (by making it think it's not on the ground).

Elater lecontei has reproduced

Found a wireworm in its enclosure today. I was starting to worry it hadn't mated.

Also, I got to see it naturally active again. Came out around midnight, fed on blueberry until sated, walked around for like a minute or two (I suspect it was seeking damper conditions as I hadn't misted in a while) and then went back under its potsherd to sleep. Apparently it's one of those bugs that's awake only when necessary.
