Mr Bugman,
I notice these flies mainly during the summer months…they’re not prolific, nor do they sting or bite…I’ve always just been curious as to what name and type of fly they are.

Ensign Wasp

Hi Mark,
The Ensign Wasp, as its name implies, is not a fly.  These parasitic hymenopterans lay their eggs in the ootheca or egg cases of cockroaches, helping to control the numbers of the infesting insects.
