Pitch moth

The term pitch moth refers to certain small moths whose caterpillars feed on pines. The feeding action causes the pine tree to shed its resin, which forms pitch-like masses on and under the tree. There are several species of "pitch moths" and not all are closely related:

In the clearwing moth family (Sesiidae)

 * Synanthedon pini (pitch mass borer)
 * Synanthedon sequoiae (sequoia pitch moth)

In the snout moth family (Pyralidae)

 * Dioryctria amatella (southern pine coneworm)
