Pelecinid Wasp?

[bugsmich]

I'm pretty sure this is a pelecinid wasp, but just wanted to confirm.
I see these wasps are common around Michigan, but I've just never seen one before. The picture I uploaded is more focused in on the wasp so I used this one, but I have another picture that shows the ovipositor is much larger than I have seen in other pictures of this type of wasp. Are the ovipositors longer with the female?

Greetings,

Yes, your specimen is a female of Pelecinus, probably P. polyturator. The long body segment is the greatly elongated abdomen. Males of this species are very rare in the north and don't have the elongate abdomen. The females are able to reproduce parthenogenetically, hence the relative rarity of males. Neat insects!

Cheers!
