| Satyrium acadica (W. H. Edwards, 1862) |
| Status: Uncommon to common local resident |
| Flight Period(s): One flight, which in Nebraska peaks in late June/early July. There are records from 23 June – 18 July. |
| Range: This butterfly is found in the northern half of the United States and southern Canada from the east coast west to eastern portions of Colorado, Wyoming, Montana and British Columbia. In Nebraska it is widely distributed throughout the state, but has yet to be found in the southeastern counties. |
| Larval Hostplant(s): Various willows (Salix sp.) |
| Overwinter: As an egg |
| Commentary/Habitat: The Acadian Hairstreak rarely strays far from riverbanks and channels and low road ditches where willows grow. Adults nectar on milkweeds, and can also be found perching on the hostplants (tapping willows can be productive) or the tops of other vegetation in the area. They normally do not appear to be common, but on one occasion more than a dozen were sighted in a small area in the late afternoon (5:00-6:00 PM), and a thorough search of the area the next morning yielded not a single individual. The species may be more common than sightings indicate. |
| Similar Species: Easily separated from other hairstreaks in markings and habitat. |
