Stray beetle

We had an unexpected addition a couple of days ago.   My husband said he found one of my beetles in the laundry room.  He handed it to me, and it was a tiny bit larger than the ones in my drawer, but I looked closely and it sure looks like the same type of beetle.  I'm no beetle expert, but I decided to put him in the drawer with the other beetles anyway.  The only thing I can think is that he started as a mealworm in the laundry I do for the wildlife clinic, and fell out and did his molting in my laundry room.  I guess the conditions for beetle-growing don't have to be very precise!

I've also had one more pupa morph into a beetle.  They sure are taking a long time!  I get four or five more pupae each day.  Maybe it's like a watched pot, since I look several times a day.
