Grote's buckmoth
Hemileuca grotei Grote & Robinson, 1868
Family: Saturniidae
Subfamily: Hemileucinae
Identification: Small. Male abdomen is black with a red tip, female abdomen is black. Upperside of forewing is brown; hindwing is darker brown to black. Each wing has a cream-colored band which may not be complete; some individuals have only a few spots. Where the forewing band is present, it is divided by the white-centered cell spot.

Life History: Females lay their eggs in rings around twigs of the host plants. Eggs overwinter and hatch in March or April.

Fully-grown caterpillars wander for a few days before spinning a cocoon in leaf litter on the ground.
Flight: One brood from September-November.
Caterpillar Hosts: Texas live oak (Quercus fusiformis), Nuttall oak (Q. texana), blackjack oak (Q. marilandica), Gambel oak (Q. gambelii), Emory oak (Q. emoryi), and scrub live oak (Q. turbinella).
