Life Cycle of the Gypsy Moth

Hatch stage
HATCH STAGE
The timing of the hatch is effected by warm weather in the spring. This is usually from early May to July. Once the hatch begins most eggs hatch within a week. Larvae start out only 1/8 inch at hatch and end up about 2 to 3 inches long. After they hatch they move up into the tree producing a thin line of silk behind them. When the wind blows it picks up the thread and the young larvae attached to it. This is how the larva move other locations. This is called 'ballooning' and is the way gypsy moth larva spread from tree to tree.
