Phoebis philea

This is a big sulphur butterfly, and males and females look different. On top, the male is a strong yellow, sometimes leaning toward yellow-orange. Each front wing has a wide orange to red-orange band across the middle, and the back wings have orange along the outer edge. Females are larger than males and come in two color forms, one pale off-white and one yellow to yellow-orange. Each female front wing has a thin dark edge, a small solid black spot near the middle, and a broken, slanted line of black marks running in from the tip. The yellow female form has red-orange on the outer part of the back wing. Underneath, both sexes are yellow to orange-yellow with small brownish spots. The pale and darker female forms are linked to wet and dry seasons, and dry-season butterflies tend to have more spotting underneath.

Sources describe it as a resident butterfly of the warm Americas, from southern Brazil north through Central America and the Caribbean (Puerto Rico is named) to peninsular Florida and the Florida Keys. It also turns up along the Gulf Coast and in the southwestern United States. In south Texas it shows up now and then rather than living there all year. In some years it spreads for a while into northern Florida. Strays have been reported far to the north, with Colorado, Minnesota, Wisconsin and Connecticut named as very rare records.

It lives in open, low-lying places. The sources name gardens, parks, neighborhoods, forest edges and roadsides. It does well in places people have changed and is often seen in towns and yards.

Adults are strong, fast fliers that often fly high. They drink nectar from many kinds of flowers. Their long mouthparts let them reach nectar deep inside tube-shaped or funnel-shaped blossoms.

Like other butterflies, it goes through egg, caterpillar, chrysalis and adult stages. Females lay pale, spindle-shaped eggs one at a time. The caterpillar is green to yellow, with dark stripes along its sides and many tiny dark dots, and it tends to feed on flowers more than leaves. The chrysalis ranges from green to pink.
