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.

Your letter to the bugman:  This guy reminds me of the hawk moths that frequent our petunias! But he’s not exactly like the ones on your page.  What is he!  He’s about 1.5 inches long.

Tiger Swallowtail Caterpillar

Dear Robin,
There are several different species of Tiger Swallowtails and they all have similar looking caterpillars.  South Dakota is included in the BugGuide data for sightings of the Eastern Tiger Swallowtail.  Its coloration indicates this Eastern Tiger Swallowtail Caterpillar is prepupal.

Your letter to the bugman:  Found this caterpillar and can’t figure out the type! Small, like the width of a thumb. Strange head. Thanks for the help! Found on a recently fallen oak tree, still with live leaves.

Emperor Caterpillar

Dear Ryan,
This is an Emperor Caterpillar in the genus
Asterocampa and here is a BugGuide image for reference.  We don’t believe they feed on oak.  Is there a hackberry shrub near where the oak fell?

Parsley Worm or Black Swallowtail Caterpillar

Dear Tina,
This is a Black Swallowtail Caterpillar, and some common names are “Dill Worm, Parsley Worm, Celery Worm, Carrot Worm, Fennel Worm” according to BugGuide, because “The common names for the caterpillars vary because they can be found on many important cultivated plants in the Carrot Family. Pick the host plant, add the word ‘worm’, and you have another common name that has probably been used and published somewhere.”

Baron Caterpillar

Dear Dean,
We believe this is an Baron caterpillar from the genus
Euthalia, and to the best of our knowledge, it is not poisonous.  There is an image on Butterfly Circle and one on FlickR to support our identification.  A Check List of Butterflies of Indo-China verifies the genus is present in Laos.
