Dear Curious Bug,
This is a Smeared Dagger Moth Caterpillar,
Acronicta oblinita, also known as a Smartweed Caterpillar.  Interestingly, we located another image online on All Posters that is feeding on a lotus leaf.  According to BugGuide, the caterpillar feeds on “A variety of forbs, shrubs, and trees” and “Caution, larva may ‘sting’ if handled.”

Hello. I recently found this strange looking creature which looks like something out n of this world! It looks like a sea urchin looking creature in my back yard . It was just sitting on my trashcan. It is a bright green color and about the size of a dime. It is super sticky and would not respond to my touch or a few drops of water being dropped on it. I have been monitoring it all day and it has not moved a bit. Please take a look at the photos.

Beutenmueller’s Slug Moth Caterpillar

Dear Victor,
This amazing looking caterpillar is a Beutenmueller’s Slug Moth Caterpillar,
Isochaetes beutenmuelleri, which we quickly identified on BugGuide thanks to an awesome series of images.  BugGuide also indicates another appropriate common name “Spun Glass Slug Moth.”  Many members of the family of Slug Moth Caterpillars are capable of stinging.

Just the obvious questions of “What the blank is this?” and “Can it hurt me?” come to mind when looking at this. It caused my sister’s adrenaline to pump and just about everyone else’s skin to crawl, but I suspect it’s a harmless (to humans) caterpillar. Unless you eat it maybe?

Dear Jack,
This is the caterpillar of a White Marked Tussock Moth,

Tiger Swallowtail Caterpillar

Tiger Swallowtail Caterpillar

Dear Poppy’s,
This is one of the Tiger Swallowtail Caterpillars, and based on your location, our best guesses are either a Pale Tiger Swallowtail Caterpillar (see image on BugGuide) or a Western Tiger Swallowtail (see Bugguide for image).  The orange coloration indicates that this individual is nearing the time to metamorphose into a chrysalis.
