Least Skipper takes nectar from ox-eye daisy
The least skipper is a weak flyer often found flitting about in low grass and foliage throughout the US east of the Rocky Mountains. They can be incredibly abundant in some years. I find them most often near watercourses or damp, low lying areas.
Identification: Antennae are short, banded with black and white alternating. Upper side of forewing is orange with a wide, diffuse black border at the outer margin; hindwing is yellow-orange with a wide black margin. Underside of forewing is black with orange borders at the tip and leading edge; hindwing is yellow-orange.
Do least skippers love dandelion?
All adult true skippers have six well developed legs. Their eggs are tiny, usually less than .1mm. Most skipper caterpillars are green and tapered, and the neck appears constricted. The caterpillars weave silk and leaves into a daytime shelter for protection. Most pupate in loosely woven cocoons. The chrysalises are often coated with a powder or bloom. Chrysalis and caterpillars may overwinter.
Skipper butterflies can be divided into five subfamilies:
