New Jersey Butterflies

Striped Hairstreak

Satyrium liparops

Identification: Very small—size of thumbnail. Almost never seen with wings open. Below: FW and HW grayish-brown with numerous widely separated white lines making it look somehow more "striped" than Banded and Hickory hairstreaks. A good field mark is the large orange cap on the blue spot at the HW tails. Similar hairstreaks: Banded and Hickory both lack the orange cap on the blue spot.

NJ Status and Distribution: Resident. Uncommon to rare but widespread throughout NJ.

Habitat: Wood edges and openings close to food plants. Can be attracted to gardens that are near woods with food plants. Likes to nectar at milkweeds (Asclepias spp.) and dogbanes (Apocynum spp.).

Flight Period: Early June—late July (occasionally into August). Extreme dates: North Jersey 6/7—8/24; South Jersey 6/2—8/3.

Larval Food Plants: Apparently a wide variety of woody plants but primarily the genera Prunus (cherries) and Vaccinium (blueberries). Most Striped Hairstreaks in northern NJ have been found in the vicinity of Black Cherry, a common and widespread native tree.

Overwintering Stage: Egg.

Best Locations: Combs Hollow Preserve, Black River WMA, Lakehurst RR.

Comments: Seeing a Striped Hairstreak (any hairstreak, really) invariably brings a smile to the face of every butterflier.
