Taking some pics of a bee-fly today when much to my suprise it stuck it's tongue (or whatever it is called) out of it's proboscis- I thought the proboscis was it but these obviously have quite a reach.

Excellent photos, Brian!

The fly's proboscis is made of a dorsal labrum covering, internal stylettes (epipharynx, mandibles), {reduced maxillae?}, and a ventral labial sheath. The stylettes form the food and salvia canals. I have no idea what mechanism allows the extension to occur...

Anyone have an explanation?

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
