Egg ID

I found these in a stack of wood. Around 3-4mm in length, looks as though they are joined by silk?

Hello Sebastian,

They aren't 'eggs' but the puparium of a species of Diptera (Fly) These are most likely parasitic flies that emerged from a lepidopterous larva. Not all larvae die immediately on the emergence of the parasitic larva and it may have crawled off.

If you still have them, hang on to them, and see what emerges.
