No Taxon Unidentified Eggs, Larvae, Pupae & Hosts
Since rearing is difficult without many available Spider hosts or Spider egg-sacks, the best way to identify your Mantidfly eggs is to catch the adult female in the act of laying them. (see the examples below)
Specimens may otherwise be identified through DNA testing. Consult with BOLD Systems (1) for details.

Climaciella brunnea:

Dicromantispa sayi:

Zeugomantispa minuta:

On the other hand, if individual larvae are found on a female Spider that is about to lay eggs or if an egg sack is found with one (larva or pupa) inside, then the rearing-to-adult may be possible.

Newborn larvae are capable of crawling off to find a host Spider.
