Phratora purpurea, the aspen skeletonizer, is a species of leaf beetle in the family Chrysomelidae.

It is found across North America, including Maryland,[1] New York, Ontario, British Columbia, and the Northwest Territories.

[5] Cavey (1994)[1] provided detailed notes on the life history of populations of Phratora purpurea subsp.

Eggs are laid in clutches of 6–15, arranged in two rows on the underside of host plant leaves (in this case P. grandidentata).

When they pupate, they leave the host plant and presumably find a site in the soil until the adult emerges in late summer.
