Oak Hairstreak (or "Northern"
Oak Hairstreak, also formerly called "Northern Hairstreak") (Satyrium favonius) Fermilab, Kane County, Illinois July 11, 2008 We are at the northern edge of
the range of this species. This individual was nectaring near the
bigs woods western edge, where I often see Banded Hairstreaks. A bit of
the upper side of the opposite wing shows due to the wing being
slightly curled, not having fully expanded. |
