Tiger Swallowtail Caterpillar with Osmeterium

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
ugGuide.

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.

Mourning Cloak Caterpillar

Mourning Cloak Caterpillar

Dear Curious,
This is the caterpillar of a Mourning Cloak, sometimes called a Spiny Elm Caterpillar.  The adult Mourning Cloak is a lovely butterfly that hibernates over the winter, and they are sometimes seen flying on warm, sunny, winter days, even when there is still snow on the ground.  Before flowers begin to bloom, they take nourishment by drinking sap that flows from the trees in the spring.

Dear Bugman: Wanted to share my son’s photo of a beautiful chrysalis he found. It was on a sign in an area park. Never seen one so beautifully patterned. We looked it up and found similar pictures and believe this will become a Baltimore Checkerspot butterfly.

Baltimore Checkerspot Chrysalis

Dear MI Bugmama,
We are in total agreement with you that this is the chrysalis of the Baltimore Checkerspot,
Euphydryas phaeton, and you can see that it is a perfect match for this BugGuide image.
