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.”

Parasitized Tobacco Hornworm

Dear Steve,
Your caterpillar is a Tobacco Hornworm, and what you have mistaken for eggs are the pupae of a parasitic Braconid Wasp.

Subject:  What’s Hatching on my Super Lemon Haze?

Your letter to the bugman:  Dear Bugman,
I’m sorry to trouble you again so soon, but because I am very nervous regarding Budworms, I am trying to inspect my plants carefully every day.  Today I noticed these creatures hatching from eggs laid on my Super Lemon Haze hybrid.  They were moving around the eggs quickly and appeared to be crawling on top of one another.  What’s going on here?  Do I have a need to worry?

Telenominid Wasps hatching from Stink Bug Eggs

Dear Constant Gardener,
These appear to be Stink Bug Eggs, possibly from the Red Shouldered Stink Bug you submitted yesterday, but those are not Stink Bugs that are hatching.  We immediately suspected some Parasitoid Wasp, so we researched Parasitoids that attack Stink Bug eggs, and we found this image on BugGuide of a parasitoid in the genus
Telenomus that looks similar to your individuals and this image on BugGuide of another member of the genus.  We also located this image on BugGuide of a different parasitoid in the genus Trissolcus and this image on BugGuide of a member in that same genus, both of which have also parasitized Stink Bug eggs.  Of the latter genus, BugGuide indicates:  “parasitize eggs of Pentatomorpha.”  Your images lack critical sharpness due to soft focus, and the images taken with flash also have some “ghosting” from a slow shutter speed.  Additionally, we lack the necessary expertise to provide an accurate species or genus identification, but both genera are in the subfamily Telenominae in the family Platygastridae, and this represents a new subcategory for our site.  Furthermore, your images are excellent examples of how pests can be controlled with organic methods.

Parasitized Inchworm with Chalcid Pupae

Dear Gene,
Your “stickbug” is an Inchworm or Spanworm, the caterpillar of a moth in the family Geometridae, and they are excellent twig mimics.  What you have mistaken for eggs are actually the pupae of parasitoid Chalcid Wasps.  Here is a similarly parasitized Inchworm on BugGuide and here is an image of the Chalcid Wasp that emerged, also on BugGuide.

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.
