I'm wondering if you kept them in this ?petri dish the whole time, and did you do anything to control heat/humidity or make conditions more favorable for their development in any way?

I kept the larvae in a parts tray cubicle on my bathroom vanity top along with a few smaller larvae, some adult Laemophloeids, some rotted wood/frass, a few scraps of fungus (including a leaf covered with slime mold spores), a couple dried shrimp pellets, some rolled oats, and a couple of small earthworms. I tried to maintain some moisture, but not too much as this is obviously a desert species. After all three appeared to have died, I placed them in a small plastic parts tray cubicle just to be sure they were dead. Only one was. This one pupated and the last one molted. The temperature ranged between 65 and 70 degrees with occasional brief periods of 85 or 90 degrees when I turned on my bathroom heater before a shower.

After this one pupated, I kept a small wad of moist tissue in its cubicle and threw another local tenebrionid pupa in with it that should emerge very soon.

in all likelihod.

Hey, Tom Murray and I are getting together (first time) to explore a wooded area this morning. Want to come along?

You know I do, but I don't see how that's likely. Stop teasing!

I *knew* you would. Well, maybe someday. Bugguide field trips!!
