    Cloudless Sulphur Butterfly - (Phoebis sennae)

    Cloudless Sulphurs migrate north in warmer months, stretching their typical range across the U.S., making them a common sight in the summer.


    Staff Writer (8/30/2016): Cloudless Sulphurs are prolific in the southern U.S. and Mexico where they can produce 3 or 4 broods a year. They migrate to the north every year where the cold weather limits them to 1 or 2 per year before they return south. They closely resemble the Clouded Sulphur. Both are similar in color, but slight variations in spot placement and forewing shape help distinguish them from each other, that is if they are around long enough to observe (or photograph). Look for Cloudless Sulphurs in a variety of areas with flowers or mud/mud puddles. They are versatile and wander through backyards, construction sites, woodland edges, parks and fields in addition to tropical forests and beaches.They are strong, fast fliers and seem to rarely stop long enough to take a proper rest.

    The larvae of this species is completely yellow at first. It develops 10 black/brown bands 'segmenting' it from head to rear. These bands eventually split to allow a thin green line to create a mint Oreo cookie effect. Black dots cover the yellow body and each black & green band ends in a black dot above the legs on each side of the body. The black/green bands fade away as the caterpillar prepares to pupate. The pupae resembles a yellow-green leaf, allowing it to blend into foliage. It prefers to feed on the leaves of senna, a type of flowering legume.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
