Bartram's Scrub-Hairstreak (Strymon acis)
Bartram's is a distinctive and rare hairstreak of south Florida. Bartram's is like a more elegant version of the related Gray Hairstreak (Strymon melinus), with broader white lines, two white dots on the hindwing, longer tails, lovely pale blue fringe when fresh. Bartram's is found in dry, sandy areas where its host plant, the Pineland or Narrow-leafed Croton (Croton linearis), grows.
Navy Wells near Florida City, Miami-Dade Co., FL 6/23/10 (all photos).
There was an outbreak at Navy Wells this day and I saw about 15, in various states of wear. This individual is very fresh.
This individual is quite worn, but still shows some of the pale blue fringing on the hindwing.
Compare the Bartram's at left with Martial Scrub-Hairstreak, which is found in different habitat (along the coastline only) and lacks the two extra white spots in the center of the hindwing.
