Hi everyone,
I have a specimen of Helophilus, that could be trivittatus, but abdomen markings look different from the drawings in Sweden's syrphid fauna of Bartsch et al., 2009. Front tarsus also looks darker than the one on the illustration. I'd be thankful for any suggestions.

Normally, Helophilus trivittaus is the only one to have a yellow facial stripe, but I agree this one is weird.

Thank you, Stephane! It is really weird, maybe some kind of a hybrid. I hope to have more opinions on this.
