Queen (Danaus gillipus)

IMG_1419.jpeg

Larva

Description: Wingspan ranges from 8.6-12.4 cm, dorsal side is chestnut brown, males have black scent pad, 

                      females have thicker veins. Very rare stray to PA.

​

Habitat: Fields, deserts, roadsides, pastures, dunes, washes, and waterways.

​

Host Plant(s): In the past, only Swamp Milkweed (A. incarnata) has worked as a suitable host for Queen

                       caterpillars for us.

​

Range/Frequency: There have only ever been four sightings of Queens in the wild, in Schuykill, Lebanon,                                                Philadelphia, and Bucks County, PA. They do not breed up here, and they should be

                                considered very rare strays to the area.
