A point if I may. Eristralis

A point if I may. Eristralis Tenax seem to have a range of markings, are there any sub-divisions?

sub divisions

To quote Stuart Ball invertebrate expert on 13.03.2011
"You cannot do Eristalis on the abdominal markings - they are far to variable!"
Hope this helps.

Hovver Variability

The extent of markings on some Eristalis eg arbustorum can vary with larval rearing temperature , The key Features on Hovers (generally) are Tibial Colouring or banding , wing Pattern, Hairyness and fringes on or around eyes , and Face pattern striped etc etc. Taken all of this factors and others is often the way to deal with this difficult genus
