Any thoughts on what butterfly this might be? At first, I thought it was a Heliconius pachinus but the pinkish markings on the wings don’t seem to be consistent with that species.

Dear Jackie,
This is actually one of the Swallowtail Butterflies, probably a Ruby Spotted Swallowtail,
Papilio anchisiades.  According to Keith Wolfe who often responds to caterpillar identification queries we receive:  “This abundant and widespread swallowtail is commonly found in areas disturbed by human activities.”  We are surmising that your sighting might be associated with an eco-tourism trip.

Hi Daniel,
Thank you so much for the identification help.   I’ve been coming across all kinds of new creatures since moving from the US to Costa Rica and some are quite challenging to identify!   Thanks for doing what you do… and love your website!
Have a great rest of the day!

Correction:  Thanks to Richard Stickney of for providing us with the correct identification of this Cattleheart Swallowtail in the genus Parides.
