I don't seem to be able to cultivar the iris borer in captivity, so I'm forced to go out into the garden and harvest the wild ones.
The first is a mid-third instar (my guess) that just made it to the rhizome.
The next two are early fourth instar that have been in the first rhizome for a few days.
I'm trying to keep the one in the rhizome alive for a couple of weeks.
Thumb (dirty and clean) is mine. It takes a couple of weeks to get the nails clean.
