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?
