Abbott’s Sphinx Caterpillar

Dear Lauren,
This is a Caterpillar of an Abbott’s Sphinx Moth,
Sphecodina abbottii, and you can verify that by comparing your individual to this image posted to BugGuide.  According to BugGuide:  “Larvae start out green with a horn on the final segment. Middle instar larvae are whitish to blue-green with dark faint cross-stripes and the horn replaced by an orange raised knob on the last segment (A8). The last instars may be either brown with a “wood-grain” pattern or brown with ten pale green saddles along the back. In these late instars the knob resembles an eye.”

Probably Clouded Skipper Caterpillar

Dear Winters,
We believe based on this BugGuide image that you have a Clouded Skipper Caterpillar,
Lerema accius.  According to BugGuide:  “Caterpillars host on grasses” and since Corn is a grass, it is a possible food plant.  According to the Alabama Butterfly Atlas:  “The caterpillar is greenish-white with a mid-dorsal dark stripe and two white lateral stripes. The head is white with a black margin and three vertical black stripes on the facial region. The body is covered with numerous minute white dots.”

Underwing Caterpillar, probably

Dear Lisa & Doug,
We believe this is an Underwing Caterpillar in the genus Catocala, but we haven’t the required skills to provide you with a species identification.  Due to its size, we suspect this individual was searching for an appropriate place in which to pupate.  Of one species, the Bug Lady on the University of Milwaukee website states:  “When it’s time to pupate, they make a minimalist pupal case using silk and leaf litter.”  We would release it on the ground in a protected area with leaf litter that will not be cleared in the near future.  Many pupating caterpillars form a cocoon in leaf litter on the ground, and fastidious leaf raking in suburban yards likely produces numerous casualties.  Underwing Moths are so named because their forewings are often camouflages to resemble bark, while the underwings are brightly colored.  The moth attracts attention when flying and then disappears, thwarting a predator, when it lands on a tree trunk.

Your letter to the bugman:  Good day, can you please tell me what the name of this caterpillar is and what its moth looks like? It’s the first time ever I’ve encountered such a caterpillar on my property. The photo was taken at mid day in late summer. I have found a few iStock photos of the same variant, but it unfortunately doesn’t identify the caterpillar.

Death’s Head Hawkmoth Caterpillar

Dear Anette,
This is a more uncommon color variation of a Death’s Head Hawkmoth Caterpillar,
Acherontia atropos, a caterpillar that is more typically bright yellow and green.  The markings on the body of the adult moth are thought to resemble a skull, hence the common name Death’s Head Hawkmoth.

Hi Daniel,
Thank you very much for your reply.
It is much appreciated.

Inchworm on Curry Plant

Dear Curious Gardener,
This is an Inchworm or Spanworm in the family Geometridae.  We believe it might be
Hyposidra talaca based on an image posted to the Butterfly House website.  Though curry is not listed as a food plant, the site indicates:  “It is polyphagous, eating the foliage of many plants including the crops.”

Thank you so much for the information.
