Swallowtails are large, beautiful butterflies which have long tails like Swallows (bird). Their long tails supposedly look sort of like antennae, which confuse predators. This is why you might see Swallowtail with one or both tails missing.
Swallowtail eggs are round.
Swallowtail caterpillars have a "forked gland" called the osmeterium. This looks like a snake's tongue and gives off a rancid odor...which scares off predators.
Swallowtail crysalis are green or brown depending to what it is attached.
The Swallowtail caterpillars spin a silk "button" to attach themselves, then a silk thread which acts as a "sling" or "girdle" to hold them in place.
All types of Swallowtail Butterflies in North America overwinter in the chrysalis stage.
Adult swallowtails feed on flower nectar. Caterpillars feed on a variety of plants.
