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.

Your letter to the bugman:  Found this in the back yard.  Looks like there maybe eggs on its back.  Is it going to mess up my garden?

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.

Subject:  Robber Fly Identification

Your letter to the bugman:  Yesterday, I found a robber fly on the bush outside my house.  I’ve never had the opportunity to see one so close, especially while it had found a meal!  I’ve been trying to identify what species of robber fly this might be.  I think it might be a Red-footed Cannibalfly, but I’m not sure.   I’d love some help confirming the species of both the robber fly and its dinner!  Thanks!

Red Footed Cannibalfly eats Leaf Footed Bug

Dear Renee,
We agree that this Robber Fly is a Red Footed Cannibalfly, or at least another member of the genus
Promachus, the Giant Robber Flies.  The prey is a Leaf Footed Bug in the genus Leptoglossus, and the light tips on the antennae lead us to believe it is likely Leptoglossus oppositus which is pictured on BugGuide, or possibly Leptoglossus fulvicornis, which is also pictured on BugGuide.  According to BugGuide, the latter feeds on “Magnolia fruit” and the former “can be very common on catalpa pods” according to BugGuide.  Alas, other diagnostic features for the Leaf Footed Bug are obscured by the Red Footed Cannibalfly.  Do you have either a magnolia or a catalpa nearby or another camera angle that shows more of the Leaf Footed Bug? 

Thank you so much for taking the time to respond to my email!  Unfortunately, the only other picture I took was not clear.  I know there are Southern Magnolia trees in the neighborhood.  I don’t think I’ve seen any catalpa in the immediate neighborhood, but we do have them here in Maryland as well.  Just a few days after my first sighting of the Red Footed Cannibalfly, one appeared on the edge of my window that I had the chance to watch again!
Thanks again!
Renée

Subject:  Hey Bugman
Geographic location of the bug:  Arizona

Time: 09:22 AM EDT
Your letter to the bugman: I’m filming in southern Arizona and came across this wasp (?) pouncing on a cricket. It had the most vibrant, cobalt blue coloring, almost metallic in its sheen. It was about 1.5” in length.
So tell me: what’s that bug?!
Sincerely,

Steel Blue Cricket Hunter and Cricket

Dear Tomás,
You had nearly every word in this predator’s name in your letter.  This is a Steel Blue Cricket Hunter,
Chlorion aerarium, and it is a marvelous addition to our Food Chain tag.  According to BugGuide:  “Females mass-provision several serial cells, each containing from 2 to 9 nymphs or adults of Gryllus pennsylvanicus. Prey are transported on the ground, venter-up, with the wasp’s mandibles grasping the antennae of the cricket.”
Please do us a favor in the future and submit your images using our standard form that you can access by clicking the Ask WTB? link on our site, though we in no way want to discourage you from submitting such excellent images via normal email channels.  Using our form makes it easier for us to create our postings in a uniform manner.

Subject:  Stinbug sucking on a monarch caterpillar.

Your letter to the bugman:  My wife was so excited to see a monarch caterpillar in our garden today (8/9/2018), only to discover that its “friend” was sucking its insides out.  I could tell the vampire was a true bug, but I had thought they mostly drank plant sap. How specific are they? Does it specialize in monarchs or does  feed  other larvae? Thanks! You guys are awesome!

Spined Soldier Bug preys on Monarch Caterpillar

Dear Mark,
While most Stink Bugs feed on fluids from plants, one subfamily, Asopinae, is predatory.  We believe we have correctly identified your Predatory Stink Bug as
Apoecilus cynicus thanks to this BugGuide image.  According to BugGuide:  “mostly feeds on caterpillars” but luckily they do not limit their diet to solely Monarch Caterpillars so relocating the Predatory Stink Bug far from the milkweed, perhaps in the vegetable patch, would be our solution to repeating this scenario in the future. 

Thank you Daniel! I was poking around insect sights too and came up with the spined soldier bug, Podisus maculiventris. Known to prefer lepidoptera larvae. Also has the dark abdominal tip.

Hi Mark,
We agree that you have provided us with a correction.  The Spined Soldier Bug is another member of the Predatory Stink Bug subfamily, and this BugGuide image is a good match, and the BugGuide description “Black streak on wing membrane + spined humeri are diagnostic” matches your image.  Thanks for bringing this misidentification to our attention.
