Summary
Brown lacewing eggs (Planipennia: Hemerobiidae) glued to the top of hairs of maize leaves can be seen as an intermediary evolutionary step between depositing the egg directly on the substrate (as in most neuropteroid families) and the protective behavioral adaptation of depositing the egg on a long thin pedicel (as e.g. in the Chrysopidae).
