18/04/2011, my garden, Kapellen, Belgium. Much larger than other specimens of
B. johannis I found earlier this month. ID'able? Thanks in advance!

I also have seen these larger Bibionidae in the past few days and assumed they were
Bibio marci (but I am not an expert).

Thank you for your answer! I checked this key (http://www.diptera-amateur.nl/Bibiodae.pdf) and I think you are right.
