Double antennae’d Diprionid!

Hey there! I thought I’d send in some pics of a very interesting sawfly I found a couple months back, but only got to keying a couple weeks ago. Seems this little Diprionid has forked antennae! Really it only has two antennae, with only two scapes and pedicels, but four flegelli. Do you think this is normal for the species, or did I stumble upon a mutant? It’s got my entomology professor (and me!) baffled.
As always, loving the site! It really helped me stay motivated in my Entomology class. Thanks for all your work maintaining it!
