Except perhaps an injunction to my fellow emergent adults: remember your larval years!
A record would spend years in larval form as an acetate, the big waxy master from which copies were made.
Holometabolous: having a complete transformation; with egg, larval, pupal and adult stages distinctly separated.
Paedogenesis: reproduction in the sexually immature or larval stage.
Of course, the parasites are not sexually mature, since nearly all of them are Cercari or larval trematodes.
Ultimate: last or final: that larval stage just before pupation.
There is, however, no doubt that the insect passes the winter in the larval condition.
The ant-lion was the larval form the lace-wing fly, of course.
The species I have most frequently found is, I believe, the larval form of the Tortrix viridana.
In the skin of a larval salamander they are quite conspicuous.
