Tiger Swallowtail Caterpillar with Osmeterium

Tiger Swallowtail Caterpillar with Osmeterium

Dear Abby,
This is a Tiger Swallowtail Caterpillar and it has extracted its osmeterium, a forked organ that produces a foul odor to deter predators.  What you have mistaken for “yellow giant eyes” are actually spots that resemble eyes, another defense mechanism to protect the docile caterpillar against predators.

Tiger Swallowtail Caterpillar with Osmeterium

Dear Johnnie dex,
This is a Tiger Swallowtail Caterpillar, and it will eventually become an adult Tiger Swallowtail, a large yellow and black striped butterfly.  Your individual has everted its osmeterium, the forked organ that emits a foul odor, acting as a defense mechanism when the caterpillar feels threatened.

Thank you Daniel,
I had also identified the caterpillar as that of a tiger swallowtail. Although sorta creepy
looking I’m glad I left the caterpillar alone to go its way as eventually a butterfly may result.
Thank you for your quick response.
John

Dear Daniel and Sophia,
We believe your chrysalis belongs to an Anise Swallowtail based on its similarity to this image posted to B

Tiger Swallowtail Caterpillar

Tiger Swallowtail Caterpillar

This is the caterpillar of a Tiger Swallowtail, and what you have mistaken for a tongue is a retractable organ called an osmeterium that gives off a foul odor.  The odor coupled with the false eyes may give predatory birds the illusion that the tasty caterpillar is actually a much larger snake that could be dangerous to a bird.  Your submission will post live to our site later in June while we are away on holiday.

Spicebush Swallowtail Caterpillar

Spicebush Swallowtail Caterpillar

Dear Nathan,
This is the Caterpillar of a Spicebush Swallowtail,
Papilio troilus, and most of the images on our site are more mature caterpillars, including many that are turning orange just prior to pupation.  Your earlier instar can be compared to this image on BugGuide.  According to BugGuide, preferred food plants include:  “Spicebush (Lindera benzoin), Sassafras trees (Sassafras albidum), Pondspice (Litsea aestivalis) Red, Swamp and Silk Bays (Persea spp.); perhaps prickly ash (Zanthoxylum americanum), Tulip tree (Liriodendron tulipifera), Sweetbay (Magnolia virginiana), and Camphor (Cinnamomum camphora).”  The adult Spicebush Swallowtail is a beautiful butterfly.
