A few days ago while I was getting photographs of Maple-leaf Hydrangea, a Fiery Skipper (Hylephila phyleus) was resting on one of the Hydrangea leaves and seemed to want attention. Here it is in all its handsome golden glory.
For some, skippers are a confusing family in the group of flying insects called Lepidoptera. All moths, and skippers are also butterflies. The most reliable difference I can see in these three families is in the antennae. Butterflies have antennae that are very thin with a knob or thicker end. Skippers, much like butterflies, have very thin knobbed antennae, but the knobs are tipped with distinct hooks. In this photo the hook is there pointing off to each side. Moths, particularly males have comb-like antennae. The female moth’s antennae is much more narrow and spindly.
Butterflies, skippers, and moths use their antennae for similar purposes, including smelling and navigation. They use both antennae together, helping to find their way.
