Zerynthia Polyxena - Development

Development

The adults are active for no more than 3 weeks. The females lay their eggs singly or in small groups at the bottom of the host plants. The eggs are spherical and whitish at first, bluish-colored before hatching. The young caterpillars feed at first on flowers and young shoots, while after the second moult they feed on leaves. The pupae stay linked to a support by a silk belt for wintering and the new adults hatch the next spring.

Famous quotes containing the word development:

    This was the Eastham famous of late years for its camp- meetings, held in a grove near by, to which thousands flock from all parts of the Bay. We conjectured that the reason for the perhaps unusual, if not unhealthful development of the religious sentiment here, was the fact that a large portion of the population are women whose husbands and sons are either abroad on the sea, or else drowned, and there is nobody but they and the ministers left behind.
    Henry David Thoreau (1817–1862)

    The experience of a sense of guilt for wrong-doing is necessary for the development of self-control. The guilt feelings will later serve as a warning signal which the child can produce himself when an impulse to repeat the naughty act comes over him. When the child can produce his on warning signals, independent of the actual presence of the adult, he is on the way to developing a conscience.
    Selma H. Fraiberg (20th century)

    I could not undertake to form a nucleus of an institution for the development of infant minds, where none already existed. It would be too cruel.
    Henry David Thoreau (1817–1862)
