Pelecinid

Pelecinid

This is a Pelecinid, a parasitic wasp in the family Pelecinidae, and it is the first example we have ever received from outside North America.  According to BugGuide:  “One North American genus with only one species: Pelecinus polyturator Drury 1773. Worldwide, there is only one extant genus, Pelecinus, with three recognized species (Johnson and Musetti, 1999):
Pelecinus polyturator (North America, Central America, South America)
Pelecinus thoracicus (western Mexico)
Pelecinus dichrous (South America)
The family was much more diverse during the Mesozoic era (Beetles in the Bush).”
We are not certain which of the South American species your individual represents.  Pelecinids prey upon the subterranean larvae of Scarab Beetles, and the female uses her long, flexible abdomen to lay eggs underground in proximity to the Scarab larva.  Beetles in the Bush has a very nice posting on the genus with this information:  “
Pelecinus polyturator is the only North American member of the family Pelecinidae, which itself contains only two additional species that are restricted to Mexico and Central/South America. It wasn’t always this way—fossils assignable to the family and representing 43 species in a dozen genera have been found as far back as the early Cretaceous (121–124 mya) across North America, Europe, and Asia (Grimaldi & Engel 2005). Surely this represents just the tip of the iceberg of Mesozoic and early Cenozoic pelecinid diversity, making today’s three species the last representatives of a once great lineage—’living fossils’ some might say.”

Thank you so much for your answer!
I will definitely make a donation for you guys.
thank you again.

Dear Rehan,
This is an American Pelecinid, a parasitic wasp that uses its long abdomen to lay eggs on or near subterranean Scarab Beetle Larvae which serve as food for the developing Pelecinid larva.

I found this yesterday in an old pot.
Live in Fort Collins, CO.
I am afraid I killed it, even though it bothered me to do so, but it looked somewhat dangerous!
Have never seen anything like this! A friend in Mexico sent me news of Panorpa nuptialis… “flying scorpion” but I am not sure it is enough similar…
Ideas?

Dear mes,
This is an American Pelecinid,
Pelecinus polyturator, the only member of its family in the continental United States.  This parasitic wasp uses its long abdomen to deposit eggs underground in the proximity of Scarab Beetle Grubs which the larval wasps eat.  American Pelecinids are not known to sting, but whenever we write that an insect is harmless, or not aggressive, someone writes in to dispute us.  In our opinion, this beneficial insect was killed unnecessarily, and we are tagging the posting as Unnecessary Carnage and we hope that you will be understanding if you encounter another American Pelecinid.  This is most definitely not a Scorpionfly, which is how Panorpa nuptialis is classified.

THANK YOU for this post, and for the education.
I am generally not squeamish around insects (having lived 17 years of my adult life in Mexico) and I sincerely regret falling into the “ew” category with this American Pelecinid. I was feeling mother bear I think…
Thank you so much for the identification which I will post around to try to atone for having lost this one!
Thanks for the good work you do
Mes

I found this bug outside my garage window. I trapped it in a glass bowl. After taking a photo I let it go. I have not been able to find out what it is and I was hoping you could.

Hi Christian,
This is a very excellent photo for identification purposes.  This is a female American Pelecinid, a parasitic wasp that pushes its long abdomen into the ground to lay eggs on the grubs of Scarab Beetles.  The beetle grub provides food for the developing American Pelecinid larva.

Hi, I have never taken a photo of a bug before but this one was something I have never seen before. This bug was walking on my car on a cool summer day (August 4, 2012) in Grand Forks, North Dakota. We never have ”strange” bugs here because of the harsh winters (I think) so when I saw this I guess I kind of freaked out.

Dear Mrs. Reiser,
This is a female American Pelecinid, and your description of it being “strange” is very appropriate since it is the only member of its family found in North America.  The female American Pelecinid uses her long, flexible abdomen to lay eggs underground on or close to the subterranean grubs of June Beetles.  The American Pelecinid is classified as a parasitic Hymenopteran, an insect order that contains wasps and bees, however the American Pelecinid does not sting and is not a threat to humans.

A quick survey brought some suggestions… one of which was an ichneumon wasp. Are we right? This guy landed of the window of our business after a nasty hail storm today in Six Lakes, Michigan.

Hi Gina,
Ichneumon Wasp is a good guess, but not correct.  This American Pelecinid is the only member of its family found in North America, and like the Ichneumon, it is a parasitic Hymenopteran.  The female uses her long abdomen to deposit eggs underground and the larvae feed upon the grubs of June Beetles.
