The giant swallowtail butterfly returned to my Southwest Florida garden a few weeks ago and left behind eggs! This is the first time I have had her visit the garden since Hurricane Ian in 2022. The wild lime is doing well – I have plenty of food for the caterpillars.

I was able to find four caterpillars on the tree, which have been put into my butterfly house, so we can watch them grow.

The caterpillar resembles that of bird poop, which helps when they are smaller as they sit on the top of surfaces in plain view.

According to the University of Florida, the giant swallowtail larvae have an osmeterium, “an orange, or reddish Y-shaped eversible gland,” that is used to wipe against small predators, such as ants and spiders. When the caterpillar is in its fourth and fifth instars it contains a highly noxious, pungent mixture of chemicals, which smells like rancid butter.
