Eristalis pertinax

Tapered drone fly

Its name comes from the noticeably tapered, wasp-like abdomen of the male, a bluff used against predators despite the fly having no sting at all.

Look for entirely yellow front and middle feet and a pair of orange-yellow spots on the second abdomen segment; males have a pointed, tapered abdomen.

Larvae are aquatic "rat-tailed maggots" that breathe through a long tube while filter-feeding in stagnant, nutrient-rich water such as ditches and manure pools.
