'Olive' Juniper Hairstreak |
|
|
  |
 |
|
|
| Mitoura gryneus gryneus (Hubner, [1819]) |
| Status: Uncommon to abundant local resident |
| Flight Period(s): At least double brooded. May 1 and July 4 are typical flight dates at Harlan County reservoir. It is recorded in the state from 6 April – 24 September. |
| Range: Subspecies gryneus is found from the New England states south almost to Florida and west to southern Minnesota, Nebraksa and most of Texas. In Nebraska it is currently found in the southern half of the state west to Frontier County. |
| Larval Hostplant(s): Junipers (Juniperus species) |
| Overwinter: As a pupa |
| Commentary/Habitat: This butterfly appears to be expanding its range westward utilizing cedar shelterbelts and pastures invaded by cedars. It was formerly separated from subspecies siva by quite some distance, but this gap is being bridged by colonists of both subspecies. They now meet in the loess hills of southcentral Nebraska and at Nebraska National Forest at Halsey. While often not apparent, the presenc e of this hairstreak can often be confirmed by tapping cedars in which they rest. First generation adults take nectar from chokecherry and plum. Second brood adults (late June-early July) are sometimes brown dorsally. |
