This tree fell down in a recent storm and is known as a Manitoba Maple. This photo is taken of two of the several black yellow winged dragonfly scorpion like taled flyer. Behaviour of which is interesting and peculiar caught the eyes of many… They appeared to be mating or birthing or fertilizing… Hard to say if the tentacles at the end of their tales were their own or coming out…or if the green thick fluid like stuff was a placenta or mating fluids or ? Very bizarre as they seemed to be labouring if not pleasuring. One I thought was birthing actually burrowed it’s once widened tail tip into a hole in the bark made by termites….nestled it there and rested. A couple of these bugs looked rather fresh, young, and of the brighter yellow and reddish brown, one somewhat curled up and drying off …I wondered if was born recently. A couple of the bugs were blacker than others, almost all black and their tails so black you would hardly notice them in the shadows of the tree pieces or against the earth.
I live in northwestern Ontario bordering with Manitoba. We just had a lot of rain, 44mm this past weekend.

Two Giant Ichneumons Oviposit

Two Giant Ichneumons Oviposit

Dear Curious C,
In your image, you have captured two different species of female Giant Ichneumons in the genus
Megarhyssa, sometimes called Stump Stabbers, and each is in the process of laying eggs or ovipositing.  Giant Ichneumons are parasitoid wasps and their host insects are the wood boring larvae of Wood Wasps in the subfamily Tremecinae, including the Pigeon Horntail, that feed on the wood of deciduous trees.  The smaller brown and yellow individual is Megarhyssa macrurus, and the larger, black and yellow individual is Megarhyssa atrata.

Wow! Very informative and fast ID’ing!! Thankyou so much!!:)
Curious C 😉

Hi – I photographed this wasp yesterday, and after a good bit of searching, the closest match I can find is the Black and Yellow Mud Dauber, except this wasp has yellow, not black antennae. (It was clinging to some grass, and seemed to not be doing well, as it was barely moving.) Perhaps you can help with the ID? Thanks!

Very active green insect in small groups on wood structures along the Kealia Pond boardwalk near Ma’alea, Maui, HI. Looks sort of like a cuckoo wasp but has enough differences to suggest some other species. Approximately 1″ (2.54cm) long. Active in daytime.

Emerald Cockroach Wasp

Emerald Cockroach Wasp

Dear T,
This is an Emerald Cockroach Wasp,
Ampulex compressa.  They are fascinating insects that are able to sting a Cockroach and turn it into a Zombie that can be led back to a nesting site where the female lays an egg on the paralyzed Cockroach which provides living food for her young.  Read our well researched posting to which we have linked for more information on this incredible parasitoid.

Stinging Ichneumon

Stinging Ichneumon

Dear B. Mann,
This is a Short Tailed Ichneumon in the genus
Ophion, and we believe these are the insects that folks write about when they claim to have been stung by a Crane Fly.  According to BugGuide:  “Most all Ophion larva are parasites of caterpillars.”  Your submission will not post live to our site until mid-June during our annual absence from the office.

Hi, I live just outside Shrewsbury UK, this lovely chap just came into my house long enough for me to take a photo, is it a Megarhyssa and are they native to the UK. We do get quite a few Dragonflies around our pond and at first I thought it was one of them, obviously not – ant ideas?

Ichneumon: Rhyssa lineolata

Sabre Wasp

Dear Tom,
This Ichneumon is not in the genus
Megarhyssa, but rather, we believe it is related to Rhyssa lineolata, a species pictured on BugGuide.  We found Rhyssa persuasoria pictured on Nature Spot where it states:  “It searches for the larvae of Horntails or Longhorn Beetles which have buried in fallen timber. The female then uses her ovipositor to drill down to the larvae and then lay an egg which hatches and parasitize the poor host.” 

Thanks Daniel that’s very helpful, cheers … Tom

Thank you,

This is a Stump Stabber, a Giant Ichneumon in the genus Megarhyssa, and she is laying her eggs where they will parasitize the wood boring larvae of Wood Wasps known as Pigeon Horntails.
