[Syrphidae] Opinion on identity of Helophilus

[Andrius]

  Dear colleagues,

 I  would  like  to  ask  for  your  opinion  on  the identity of this
Helophilus.  Facial  stripe  suggests  it  is  trivittatus,  but  the
markings  on  abdomen  and  tarsal  colors  are not typical.

 I  got  an  opinion  on  Diptera.info  that  "it is weird", but is it
possible to tell what kind of weird?

Thank you in advance!

Andrius
