Predatory Stink Bug Nymph eats Caterpillar

Dear Ginja ninja,
The predator is a Stink Bug nymph and we have identified it as an immature Spined Soldier Bug, a member of the genus
Podisus, thanks to this BugGuide image.  According to BugGuide:  “preys on a wide variety of other arthropods, especially larval forms of Lepidoptera and Coleoptera. known to eat Mexican bean beetles, European corn borers, diamondback moths, corn earworms, beet armyworms, fall armyworms, cabbage loopers, imported cabbageworms, Colorado potato beetles, and velvetbean caterpillars.”  We will attempt to identify your Moth Caterpillar as well, but we are surmising that since it was found on kale, it is most likely an undesirable species.

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.

Your letter to the bugman:  Encountered this Spider wasp attempting to haul off his bounty today…wolf spider. A rather large wolf spider at that.
Respect for anything that takes care of these nasty spiders for me.

Spider Wasp with Wolf Spider Prey

Dear Stefanie,
Only female Spider Wasps hunt for prey to feed the brood.  We agree your wasp is
Entypus unifasciatus, and according to BugGuide:  “Females dig a burrow that ends in a terminal chamber off of the side of a mammal burrow or large crack in the ground. The serrations on the hind tibiae are used to aid the movement of soil out of the burrow entrance. The position in which the egg is laid is unknown. Larvae feed on one large spider and, as in all Pompilids that have one generation per year, overwinter as pupae.”

Correction:  January 23, 2018
In reference to the August 22, 2018 photo of Entypus unifasciatus from Oklahoma City, OK by “Stephanie,” the host spider is Syspira sp. (Prowling spider)(Miturgidae). Of 414 host records for this species of wasp, this is the first host record (1/414, 0.02%) for this family of spider. We do, however, have the same genus and family host record for the congener Entypus aratus from Mexico. We should like to acknowledge “What’s That Bug” and Stephanie for this extremely rare and highly unusual host record. Does Stephanie have a last name to accompany this record in our forthcoming publication on spider wasps? Thank you. Keep up the good work.

Retraction of Correction:  March 4, 2019
When I first saw the image I thought it was a lycosid (wolf spider).  I sent it to an arachnologist at the CAS and he identified the spider as Genus Syspira, Family Miturgidae.  Since then I have consulted two other arachnologists, one from SDSU in CA, and they both informed me that the genus Syspira does not occur in Oklahoma.  They checked hundreds of museum records for this genus through a third arachnologist at Colorado State University and the genus does not occur in SE CO nor in N Texas.  They think the spider is in the genus Hogna (Lycosidae) but cannot be certain because, unfortunately, they cannot see the eye arrangement from the side view photograph.  I’ve sent your higher resolution out for additional study but, since the genus Syspira does not occur in Oklahoma, this is probably a moot exercise.  Thank you for your effort in aiding this identification dilemma.

Your letter to the bugman:  Can you help identify the bug in the attached picture? It looked like it was eating the other bug, and its long body reminded me of a dragonfly.  I really have no idea what it is.  Your help is very much appreciated.

Your letter to the bugman:  These two were battling it out, but the wasp won in the end. I thought it may have been a cicada killer, but this one was all black, maybe a little Blueish.

Great Black Wasp and Katydid Prey

Dear Karin,
We are thrilled to be able to post your wonderful images of a female Great Black Wasp and her Katydid prey.  The wasp has stung and paralyzed the Katydid and she it trying to get it back to her underground burrow.  She is probably climbing the table to give her some height so she can take off and glide toward her nest.  According to BugGuide:  “Provision nests (in burrow in soft earth) with Katydids or grasshoppers. ”  Also commonly called Katydid Hunters, these solitary wasp are not aggressive toward humans.

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?
The first photo was shot without a flash and the other two were shot with a flash.

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.
