Hi,
I'm currently working with Eristalis brought up from larvae or pupae. Due
to the collecting method its not possible to collect the larvae or pupae of
only one species of Eristalis and I therefore wonder if someone have some
helpful insight in how to distinguish between Eristalis tenax and Eristalis
arbustorum.

Kind Regards
Malin Thyselius
