Male Ichneumon: Lymeon orbus possibly

Dear Seth,
This is a parasitoid wasp in the family Ichneumonidae, and according to BugGuide:  “~5,000 described spp. in almost 500 genera in the Nearctic Region, possibly 3,000 more undescribed; arguably, the largest animal family, with the estimated 60,000 species worldwide (up to 100,000, according to some estimates.  Those numbers mean that species identifications can be very challenging. Your individual looks very similar to
Lymeon orbus based on this BugGuide image, but your individual lacks an ovipositor, making it a male, and your individual has a black band on the hind leg lacking in the images we have located of Lymeon orbus.  So, we are certain that this is an Ichneumon Wasp, we are nearly certain it is a male, and beyond that, we need to defer to real experts.  If you find any closer visual matches, please let us know.

What’s That Pupa???

Dear Cheryl,
We are quite certain we have a similar looking hanging pupa in our archives, but we cannot remember its identity this morning.  We are currently very pressed for time, so we are posting your image as unidentified and we hope one of our readers will be able to provide a comment with its identity.

Update:  September 17, 2018:  Thanks to comments from both Cesar Crash and Karl, we are now able to link to another Ichneumon pupa in our archives.

Your letter to the bugman:  Found this guy flying around my office at approx 8pm in early August.  Length is approx 1/2 inch.  Head is not black, though thorax mostly is.  Can’t find out exactly what kind of Ichneumon he is.  Nothing online seems to clearly match

Ichneumon

Dear Perez,
Your images would be excellent for identifying this Ichneumon if the identification of Ichneumons was an easy matter.  According to BugGuide:  “5,000 described spp. in almost 500 genera in the Nearctic Region, possibly 3,000 more undescribed; arguably, the largest animal family, with the estimated 60,000 species worldwide (up to 100,000, according to some estimates).”  The most similar looking image we could find on BugGuide regarding the shape of legs, head and antennae is in the genus
Banchus, however, the coloration is noticeably different.  Alas, we will have to post your images and tag them as unidentified.

Short Tailed Ichneumon

Dear HH,
This is a parasitoid Short-Tailed Ichneumon, probably in the genus
Ophion.  We were surprised to learn many years ago that this group is rather unique among Ichneumons in that they are capable of stinging humans.  According to BugGuide:  “Most all Ophion larva are parasites of caterpillars.”

Stump Stabber

Dear Karen,
The Giant Ichneumon or Stump Stabber is neither harmful nor dangerous, but the lengthy ovipositor is frightening looking.  This is a beneficial insect.  The female uses her ovipositor to lay eggs beneath the bark of trees infested with wood boring larvae, and the Ichneumon larva feeds on those wood boring larvae.

Stump Stabber

Dear Matt,
This is a harmless, parasitic Giant Ichneumon in the genus
Megarhyssa, a group commonly called Stump Stabbers because the female uses her long ovipositor to lay eggs in stumps and trees that have infestations due to wood boring larvae that provide food for the larval Stump Stabber.  Ichneumons are classified in the same insect order as Wasps, Ants and Bees.
