since about two months I have two pupae here, the larvae parasitized in the caterpillars of a butterfly breed, (A. urticae). Meanwhile the butterflies are hatched about two weeks ago, but the flies don't seem to hatch. In the same breed there were two Braconidae nests, they hatched at the same time as the butterflies.
What do you think how long it may take until the tachinid flies hatch ?

Regards, Volkmar

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
