Great Spangled Fritillary - Range and Life Cycle

Range and Life Cycle

This species covers a wide range over North America Stretching from Southern British Columbia, eastward to Quebec and the Maritime Provinces down south west of the Rocky Mountains to California, and down east of the Appalachian Mountains from Maine to Northern Georgia. Curiously, it does not occur in the Midwest, or in the Great Plains. Prime habitat for this species includes moist meadows and deciduous woods in the east. In the west, it prefers moist pine and oak woods and is common around woodland edges.

This species starts as an egg laid in the fall months, the caterpillar hatches from a brown egg and overwinters. It begins eating in March, generally only found on the wild violet, (Viola rotundiflora; and grows and changes in color from brown to black and produces prickly, black spines.

The Great spangled Fritilary flies quickly but pause to take nectar from a variety of blossoms including Black-Eyed Susan, Thistles, and others. Females mate in June or July and then proceed to hide, on bark, or under foliage till late August to September, to lay their eggs on the leaves of the viola. Males, which emerged earlier, in May to June, live only to mate and by this time are almost nonexistent. This species is more common in the East, int the West it is scarce, and this Western population is occasionally give species status, the Leto Fritillary, (S. leto). (Fullard & Napoleone, 2001).

Famous quotes containing the words range, life and/or cycle:

    Culture is the suggestion, from certain best thoughts, that a man has a range of affinities through which he can modulate the violence of any master-tones that have a droning preponderance in his scale, and succor him against himself. Culture redresses this imbalance, puts him among equals and superiors, revives the delicious sense of sympathy, and warns him of the dangers of solitude and repulsion.
    Ralph Waldo Emerson (1803–1882)

    What is art,
    But life upon the larger scale, the higher,
    When, graduating up in a spiral line
    Of still expanding and ascending gyres,
    It pushes toward the intense significance
    Of all things, hungry for the Infinite?
    Art’s life,—and where we live, we suffer and toil.
    Elizabeth Barrett Browning (1806–1861)

    The Buddha, the Godhead, resides quite as comfortably in the circuits of a digital computer or the gears of a cycle transmission as he does at the top of a mountain or in the petals of a flower.
    Robert M. Pirsig (b. 1928)
