Common Rose Caterpillar

We were immediately struck by the resemblance your Caterpillar has to the North American Pipevine Swallowtail Caterpillar, so we decided to research that lead and found images of the Common Rose Caterpillar, Pachliopta aristolochiae, on Wikimedia Commons that look exactly like your individual.  Images of the adult Common Rose are pictured on Butterflies of India.  The entire life cycle of the Common Rose is also pictured on Butterflies of India.

Hi we found this caterpillar on a pole in our society. This is October so the weather is slowly turning cool. My daughter is very keen on watching its metamorphosis. But we really need to know what to feed it. Otherwise we will put it back in the garden. So need a quick reply.  Many thanks.

Swallowtail Caterpillar

Dear Mrinalini,
We believe this is the caterpillar of a butterfly in the family Papilionidae, many of which are known as Swallowtails, but we cannot provide anything more specific at this time.  The Butterflies of India site has images of many butterflies from the family.

Hi! So I was just watering my lemon tree when I found this little weirdo hanging out. He’s 2 inches long and is a very thick boi. He seems to have only eaten 3ish leaves, so I think a bird dropped him or something. He was moving a bit when I found him, but he’s been completely still for the past 10 minutes. There are also these clear dot things I can’t tell if they’re eggs or not.

Orange Dog

This is the caterpillar of a Giant Swallowtail, commonly called an Orange Dog because they feed on the leaves or orange and other citrus trees.  The do not do enough damage to be considered a problem.

Hello, my sons have never seen this type of caterpillar and would love to know what it is called and more about it!

Pre-Pupal Spicebush Swallowtail Caterpillar

Dear #askingforhersons,
This whimsical looking caterpillar is a pre-pupal Spicebush Swallowtail Caterpillar.  The orange color indicates it is pre-pupal, and just prior to pupation, the normally green caterpillars often turn orange when they leave the trees they have been feeding upon to search for an appropriate site to commence metamorphosis.  Here is a BugGuide image for comparison.  Interestingly, we have many more images on our site of the caterpillars than we do of the beautiful black adult Spicebush Swallowtails with their distinctive green spots.

Orange Dog

Dear Nuck,
This is an Orange Dog, the caterpillar of a Giant Swallowtail, a butterfly native to the southeastern states of North America.  The cultivation of citrus trees in Florida provided a host plant that the caterpillars will eat, and the Giant Swallowtail expanded its range to follow citrus cultivation, eventually reaching Southern California in the late 1990s.  It is now well established in California.  You may lose some leaves, but that is a small price to pay for the joy of seeing the magnificent Giant Swallowtails gliding gracefully around your yard.

Thanks.  I love seeing the swallowtail.  Exciting. Do the caterpillars have a predator?

While they don’t have a specific predator, we imagine they can become prey to birds, which is why they have evolved to resemble bird droppings as a form of protective mimicry.

We have found a caterpillar which is new to us! It was apparently in a hurry to pupate, as soon as we housed it, it went to work. I think Mom is having the most fun here! 🙂
We are in the north central (Brewster) part of Washington State. This is a darker bluish green caterpillar with white and black eye spots and white and black collar. It turned to brown very soon after we found and housed it.

Western Tiger Swallowtail Caterpillar

Dear Elizabeth,
We believe this is a Western Tiger Swallowtail Caterpillar, but we would not rule out that it might be a related species like a Two Tailed Swallowtail Caterpillar.
