I literally had a field day Wednesday. I stopped by the side of the road to look for bugs on a patch of Purple Loosestrife, & hit photo paydirt with a bee in flight. But the road also happened to be running past a fallow field at the Rutgers ag school (Cook College) that was planted in Red Clover & was brimming with butterflies, dragonflies, & the occasional interesting weed. Perhaps not coincidentally, one of the interesting weeds was Indian Mallow, which is a larval food plant of these butterflies.  These Common Checkered Skippers (a life butterfly for me) were abundant. Wingspan ~3 cm -- small for a spreadwing skipper. Dorsal view here . Also present: Clouded Sulphur, Orange Sulphur, Monarch, at least 1 Black/Spicebush Swallowtail, Eastern Tailed-blue, & probably others I'm forgetting or couldn't ID.
