Your letter to the bugman:  This is currently on my lime tree and not moving.  I thought it was a butterfly but the head looks like a lizard or snake.

Orange Dog

That’s ok!  I found it!  It’s a skull caterpillar! A Very cool bug indeed.
Rita
I love that you get so many photos of weird bugs that you cannot answer them all.

Dear Rita,
We are not certain where you found the name “Skull Caterpillar” but we do know that Orange Dog is a commonly used name for the caterpillar of the Giant Swallowtail.  The markings on the Orange Dog, which feeds on the leaves of orange trees and other members of the citrus family, are thought to mimic bird dropping for protection.

Very interesting, thank you:)
I got the term skull caterpillar from a google search.
Sincerely,
Rita

Swallowtail Chrysalis

Dear Amber,
Most butterflies have a chrysalis that hangs downward from the tip of the abdomen from a silken button spun by the caterpillar, but most Swallowtail caterpillars have an upright chrysalis that is also supported by a silken girdle.  Your chrysalis looks like a Swallowtail Butterfly chrysalis, but we are not certain of the species.

Your letter to the bugman:  I’m assuming it may be some kind of moth maybe? But it looks so reptilian it’s creeping me out. Do you know what this is? Is it a beneficial creature to the garden?

Orange Dog

Dear doesn’t matter,
Please provide us with a “geographic location of the bug.”  According to Sciencing:  “Geographic location refers to a position on the Earth. ”  Other online sources give similar definitions.  While it is helpful to know that it was found on a “citrus dwarf mandarin tree,” we can’t say for certain that this is an Orange Dog, but that is our opinion provided your sighting was in North America.  The loss of leaves from a single caterpillar will not compromise the health of your tree.  The Orange Dog is the caterpillar of a Giant Swallowtail.

Spicebush Swallowtail Caterpillar

Dear Lisa,
The orange color on your Spicebush Swallowtail Caterpillar indicates it is pre-pupal, and getting very close to forming a chrysalis.

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:  What is this. Just found it on my parsley plant.

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.”
