The genus Hasora in the family Hesperiidae comprise a group of medium-sized fast-flying butterflies. They usually stop with wings folded closed and has a habit of returning to a same perch repeatedly.
When I was at Fraser's Hill some years ago, I observed two species - H. taminatus and H. chromus, returning again and again to the same spot on the damp walls of the bungalow that I was staying at.
This morning at TBHP, we observed a similar behaviour in H. vitta. Whilst the key in C&P4 indicates how to separate them, it may not be easy to distinguish amongst the 3 species which have white banded hindwings.
Here are shots of the 3 species, H. chromus (pardon the poor quality of the shot, as this was scanned from a slide with an el cheapo scanner) taken some time in 2001 at West Coast Park, followed by H. taminatus, shot at USR recently, and H. vitta, shot this morning at TBHP.
