Similar to the Scarce Bordered Straw, although that species lacks the prominent, almost triangular shaped, mark on the leading edge of the forewing.  The Eastern Bordered Straw has three black dots on the outer edge of the forewing and an inward notch along the darker outermost cross-line.

Can be seen flying in the sunshine, visiting flowers or laying eggs. Also flies from dusk and into the night.
The larvae can be seen from June to October.
