What is this thing I accidentally stepped on

Dear Kayla,
This very distinctly marked parasitic Ichneumon is
Rhyssa lineolata, which you can verify on BugGuide.  We wonder how many times you are going to refer to the dictionary with this information on the feeding habits that are posted on BugGuide:  “idiobiont ectoparasitoids of the immature wood-boring endopterygote insects, in our area usually larval woodwasps (Siricidae and Xiphydriidae), but may also develop as facultative hyperparasitoids using other woodwasp parasitoids as hosts or on virtually any endopterygote (some have even been cultured in the laboratory on entirely unnatural surrogate hosts).”

A friend of mine spotted this interesting insect on the side of a home the other day in Pembroke, ON. I don’t really have too many details, However, I do have an image! They’re calling it a “Dragonbee”

Male Stumpstabber

Dear However,
As much as we like the name “Dragonbee”, we are not ready to promote it as an alternate name for this male Stump Stabber, though one would probably never attribute that name to the male of a
Megarhyssa species.  The name is quite apt for the female Stump Stabber which actually stabs stumps with her long ovipositor while laying eggs that will eventually parasitize a larval Wood Wasp. We believe your Stump Stabber is Megarhyssa macrurus, based on images posted to BugGuide and the listed range data there.

I found this unfamiliar bug on my deck. I’ve never seen one before . It’s larger than the usual yellow jacket.

Elm Sawfly

Dear Sarah,
Though this Elm Sawfly,
Cimbex americana, is related to bees and wasps by being classified in the same order, the Elm Sawfly is incapable of stinging.  We received two recent identification requests for Elm Sawflies, and because the other submission included images of the living insect, we featured that posting as our Bug of the Month for June 2015 though it appears it was also selected as the Bug of the Month for April 2013.  Your submission is nonetheless quite important as we get very few submissions from Alaska.

Thank you! I saw a second one today in a driveway a half mile away. Sounds as if I should give a heads up to the entomologists at Univ. of Alaska, Fairbanks. You give me a starting place. Thanks again.

I saw this giant insect on an Italian plum in late May in Seattle. It was a warm 75 degree day. It moved slowly on the branches and the butt was pulsating. I made direct eye contact with her. She looked me right in my eyes.

Dear Bugged out,
Though it is in the same insect order as wasps and bees, this Elm Sawfly,
Cimbex americana, is perfectly harmless to humans as it is incapable of stinging.  A day earlier, we received another identification request for a “Bee with yellow tipped antennae” and we suspected it too was an Elm Sawfly.  Your images are of a living specimen and the other is dead, and we much prefer images of living insects to those of dead insects, so we decided to feature your submission as the Bug of the Month for June 2015.  The Elm Sawfly, according to BugGuide:  “hosts include elm (Ulmus), maple (Acer), birch (Betula), willow (Salix), and basswood (Tilia); adults girdle bark on twigs.”

Thanks for the info and for featuring the sawfly! The insect will live out her natural life as we choose not to kill anyone.
Thank you again!

I’ve been seeing about 50 of these guys parade my front and back yard over the grass areas. They do not seem to be harmful, and only hover over the grass areas. I did research and came across your website to find out it’s an “ichneumon wasp” according to Eric Eaton on another post. Would you happen to know where they nest or why they’re parading my lawn areas for? At first they looked like yellow jackets, but their bodies are much too skinny and orange to be. The pics I’ll include are from a few days ago. Any info would be great. Thanks.

Hi Stephanie,
We noticed your comment on the other Ichneumon posting, and we still are not able to provide a species identification for this Ichneumon.  Ichneumon Wasps do not build a nest.  They are parasitoids of a variety of insects and arthropods, and they are generally very host specific.  The female lays an egg on a host, or sometimes she uses her ovipositor to deposit eggs within the host.  The larvae then feed on the still living host.  Again, Ichneumons are not social wasps, but they are very important natural, biological controls for other insect populations, hence they are beneficial.  Most Ichneumons are perfectly harmless to humans, though members of the genus
Ophion are known to sting, but they are still not considered harmful to humans.

Dear WTB:
I was hoping you could tell me what kind of insect this is. I found it hanging out on my screen door this morning and it scared the crap outta me! It’s all different colors and has this long tail? It’s not a stinger because it could move it. All together it’s probably about 8-12 inches long. I hope you can ID it for me! Thanks so much!

Stump Stabber

Stump Stabber

Dear Audrey,
This is a Giant Ichneumon in the genus
Megarhyssa, a group that is commonly called Stump Stabbers because the female uses her lengthy ovipositor to lay eggs beneath the surface of trees infested with the wood boring larvae of Wood Wasps like the Pigeon Horntail.  We have never heard of a person being stung by a Giant Icheumon in the genus Megarhyssa, so we consider them to be harmless, though there is one group of Ichneumons in the genus Ophion with shorter ovipositors that are reported to sting people.
