Eupackardia is a monotypic moth genus in the family Saturniidae erected by Theodore Dru Alison Cockerell in 1912.

[3] The larvae mainly feed on Fraxinus species, Leucophyllum frutescens, Sapium biloculare and Fouquieria splendens.

[4] The wings, which normally span 8-11 centimetres, are black with conspicuous white post-median lines which happen to be wider in females.

In central Arizona to Mexico they are seen from October to January, and in South Texas they are seen from September to November as well as March to April.

[4] Raccoons, opossum and possibly other species of the order Rodentia tend to tear apart the cocoons of the calleta silkmoth.

[5] The cocoons of Eupackardia calleta are often used for ankle rattles and medicinal necklaces in certain American Indian ceremonies.
