Larval Hostplant(s): Yucca – Yucca glauca.
Broods/Flight Times: One early spring flight from mid-April to mid-May.
Overwintering: As fully grown larvae in a burrow in the root of the hostplant.
Habitat: Loess hills with extensive yucca growth.
Avg. Wingspan: 1 7/8 – 3 1/8 inches
Found at: Ash Hollow SHP, Swanson and Enders Reservoirs SRAs, Harlan County Reservoir, Box Elder SWMA
Similar Species: Strecker’s Giant-Skipper which is larger and flies a month later.
Notes: Probably under-reported due to it’s early flight period and remote locations. Females lay eggs on yucca leaves. Upon hatching the larvae burrow into the root of the yucca plant and leave a telltale “tent” made of frass and silk in the center of the plant which may last several years. Many records consist of finding these tent rather than the insect itself. This skipper has yet to be found in the sandhills region despite the large number of yucca that thrive there.
