Eastern Tailed-Blue

7/8 to 1 1/8 inches

Host plants include: wild pea (Lathyrus), yellow sweet clover (Melilotus officinalis) and alfalfa (Medicago sativa)

Pearl Crescent

1 1/4 to 1 3/4 inches

Host plants: several species of asters, such as Symphyotrichum pilosum var. pilosum and Symphyotrichum drummondii var. texanum

The pearl crescent is part of the brushfoot family, which includes fritillaries, satyrs and the monarch. Smaller than its cousins, this orange and black-checked butterfly is abundant from the East Coast to the Rocky Mountains. The males patrol open areas looking for females and sometimes dart out at intruders.

Common Checkered-Skipper

1 to 1½ inches

Host plants include: hollyhock (Alcea) and poppy mallow (Callirhoe)

Skippers are the sparrows of the butterfly world. There are a lot of them and it’s difficult to tell each species apart. The most widespread, the common checkered-skipper, frequents a variety of habitats across much of the U.S. Like other skippers, it has a stout body and is a strong and fast flier.

Dainty Sulphur

¾ to 1 1/4 inches

Host plants include: sneezeweed (Helenium), shepherd’s needle (Bidens pilosa) and cultivated marigold (Tagetes)

A list of tiny butterflies wouldn’t be complete without the dainty sulphur, the most diminutive of the North American sulphurs. Even its name means “small.” Found in open areas across most of the southern U.S., it has distinctive sulphur yellow underwings with three black dots.

Desert Orangetip

1 to 1½ inches

Host plants include: tansy-mustard (Descurainia pinnata) and tumble mustard (Sisymbrium altissimum)

Named for the orange patches on its forewings, the desert orangetip is common in the rocky southwestern desert. It might visit gardens with plants from the mustard family, its caterpillar host plant. If the weather is too dry for the orangetip to emerge, it may remain in its chrysalis stage for several years.

How Much Does a Butterfly Weigh?

Just how much does a butterfly weigh? Butterfly field guide author Paul Opler of Colorado State University estimates a large swallowtail weighs 0.3 gram, and smaller butterflies weigh 0.04 gram. The smallest, a pygmy-blue, would weigh only thousandths of a gram.

For comparison, a single sugar cube weighs about 3 grams.
