A genus of moths.

"G. Roesella, Spinach Moth, appears in the spring and throughout the summer. It is blackish-brown coloured. Caterpillar yellowish green. Feeds on spinach, strawberry blite, etc, and lives three or four together, under a web on the leaves".

Mr. Curtis says, that "when fully fed the caterpillars leave the plants on which they have been subsisting, and seek some crack in a tree or wall, where they spin a slight cocoon, and change to pupa; in this state they remain ten or twelve days, when the perfect insect emerges. The moth, when its wings are expanded, is about five lines long; the head, body, and feet are black, with a shining metallic appearance. The antennae are black with white rings, and the upper wings are yellow, with black edges, and about five silvery spots disposed in the shape of a cross; the under wings are blackish, and, as well as the upper, have long fringes. It is difficult to find means to destroy so minute an enemy as the present; but where it attacks spinach it is much better to pull up the plants with the caterpillars on them, and burn them; where they appear only in small quantities, hand-picking may answer very well." - Gard.
