Is it to lay eggs on prey (orthoptera) in ectoparasite or for some other reason? Is it possible to identify it? Thank you for your help.

Taxigramma heteroneura which has large and well marked spots Taxigramma stictica which has small, bilobal spots. Taxigram hilarella that has wide spots. But there are probably other criteria, others species and I think my two Taxigramma are not identifiable? I note sp.? If it succeeds in laying eggs on Pryonix kirbii's prey, will its larvae eat the prey or Pryonix larvae?

It is farther from the wing margin and more sharply angled in Taxigramma heteroneura than Taxigramma hilaralla. Those are the only species we have in America so I don't know about the other 16.
