This larva hatched from an egg laid by this adult

The adult had laid several eggs in captivity, including this one , although that egg may not be the one from which this larva hatched.

Not debris-carrying. Reared on Aphis nerii. Pupation unsuccessful, probably due to mishap during handling.

There are relatively few Chrysopid larvae in the guide with a dark median line on the head. At least one has been ID'd as Chrysopa sp., but it looks pretty different from mine. I think the rest are unidentified.
