Ovipositing insects project
I should have done this ages ago :)
Oviposition observations are quite valuable as they combine the adult (often identifiable) with the habitat where early stages develop. I could not find a project for keeping tab us these so I made one. Please add relevant observations to this project if you notice such breeding behaviour in images.
