Eastern-tailed Blue
Blue Everes comyntas
Wingspan: 7/8 to 1 1/8 inch

This lively blue to blue-grey butterfly has an orange spot on the hindwing and is the only blue butterfly in Prince William County with "tails" on the hindwing.

The Eastern-tailed Blue flies close to the ground and frequents open areas.

Eastern-tailed blues perch on low vegetation, rubbing their wings together. Males visit damp areas on the ground seeking moisture.

This pretty butterfly nectars on members of the clover family from early May through September.

Single pale green eggs with white ridges are laid on host flowers, including a variety of clovers (Lespedeza) and legumes (Fabaceae).
