Muscular head pumps give long-proboscid fly edge

A long-proboscid fly with an extra-long, tongue-like proboscis might seem to take extra-long to feed on a flower, but it actually has an advantage over its counterparts with average sized nectar-sipping mouth parts. It can suck up almost all nectar available in a flower in one go, because it has more efficient suction pumps in its head, say researchers.
