Fresh drops of spritely lemon flitting from flower to flower, the Clouded Sulphur is another beauty often seen drinking nectar alongside Monarch’s during the M’s epic migration southward.
At this time of year, late summer/early autumn butterflies find nectar at native asters, goldenrods, and non-native Black Mustard, along with a variety of garden flowers that have an extended blooming period. Clouded Sulphurs have a special fondness for Zinnia elegans, the straight species, not the over-hybridized, overly ruffled variety, where they may have difficulty finding nectar in the obscured center of the flower.
Clouded Sulphur caterpillars eat Alfalfa (Medicago sativa), White Clover (Trifolium repens),sweet clovers (Melilotus spp.) and vetches (Viceia, spp.).

Later in the day the light is so beautiful in gardens. It’s not necessarily the best time of day for capturing winged wonders in flight, but the gossamer wings of white and yellow butterflies, the family Pieridae, look especially silky and diaphanous in the oblique light of late afternoon.

Cabbage Whites are the earliest butterfly to appear in spring and one of the last sighted in fall. They are easy to ID, although some female Clouded Sulphurs and Orange Sulphurs have a white form and the Checkered Whites are very similar, yet less common around these parts.
We see far more Clouded Sulphurs than Orange and Cloudless Sulphurs on Cape Ann. Cloudeds have a lovely pinked border and silver spot on the the ventral side of their hindwings. You can tell the male from the female because when the wings are open, the male has a black border on its wing margins (as you can see in the photo below); the female’s black border is spotted with yellow and not as pronounced.
Clouded Sulphur caterpillars eat clover, alfalfa, and legumes. The photo is possibly a caterpillar of the Pieridae family, or it could be a Skipper caterpillar.
