• In the wild, the main predators of the egg stage of the Painted Lady are other insects, and their only defense is their
greenish color that blends in with the leaves that they are laid upon. Predators of the larvae stage are ants, birds,
and reptiles. Birds and reptiles are also predators of the chrysalid stage. The chrysalids use their pale brown color
to blend in with the underside of leaves, and they shake when they feel something touch them, which discourages
predators. Birds, reptiles, and frogs are the major predators of the adult Painted Lady, but the butterflies are very
sensitive to light changes and movement and can often escape their predators through quick flight.
Disposition
We do not recommend releasing any laboratory-bred animal into the wild, and especially not insects that are
considered to be pests by the USDA. We recommend that you keep adult Painted Lady Butterflies in their
habitat/cage for their entire 2 – 4 week life span.
• If you need to euthanize any larvae, chrysalids, or butterflies, one of the following steps should be taken before
disposing:
• Place the organism in a freezer for 48 hours.
• Place the organism in 70% isopropyl alcohol for 24 hours.
• A deceased specimen should be disposed of as soon as possible. Consult your school's recommended procedures
for disposal. In general, dead insects should be handled as little as possible or with gloves, wrapped in an opaque
plastic bag that is sealed (tied tightly) before being placed in a general garbage container away from students.
