This is a pupa of Megalocaria dilatata (Coccinellidae) found feeding on an aphid (Aiceona titabarensis) on a local tree (Litsea monopetala) found in Hong Kong. One day after the pupa was collected, numerous maggots emerged from the pupa as shown in the picture

One day after emerging from the pupa, the maggots turned into pupae.

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
