Ichneumon, we believe

Dear Weirdbug,
This sure looks like an Ichneumon to us, or some other parasitoid wasp, but we have not had any luck with a definitive identity.  We wish there was more detail in your image.  Ichneumons are parasitoid Wasps that are considered important biological control agents for caterpillars and other insects.  According to BugGuide:  “a great variety of hosts (mostly immature stages) is used, though most species attack only a few host types; some infest spiders and other non-insect arthropods.”   The wing veination on your individual appears very similar to the drawing on Le Monde des Insectes.

Ichneumon

Dear Stacy,
This is an Ichneumon, a parasitoid wasp, not a Crane Fly.  We suspect that many reported Crane Fly stings are actually from Ichneumons.

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.

Dead Tobacco Hornworm with Braconid Pupae

Dear Pina,
This Tobacco Hornworm or Carolina Sphinx is quite dead, but while it was still alive, it was parasitized by a Braconid Wasp.  When the wasp larvae hatched, they feed on the non-vital tissues of the hornworm until they were ready to leave the host and pupate.  The white things are the Braconid pupae.

Chalcidid Wasp

Dear Adrian,
This is a parasitoid Chalcidid Wasp, probably in the genus
Conura, formerly Spilochalcis.  According to BugGuide:  “most attack Lepidoptera pupae; a few parasitize Coleoptera (Chrysomelidae, Curculionidae) and Diptera (Syrphidae); some are secondary parasites of Ichneumonidae and Braconidae.”
