Mature
tussock moth larvae are large (30 mm) with distinctive coloration
and hairs, which can irritate the skin of pickers. Female
moths are flightless and lay large batches of eggs in a hairy
mass, which overwinter wrapped inside blueberry leaves. These
can be seen during pruning. |
| Tussock moth larvae are brightly colored. |

Small,
brown larvae hatch from the egg mass in the spring and disperse
into the lower branches of bushes. There can be two generations
per year. Scouting in the inside and bottom of bushes can
help detect larvae before they reach full size. This pest
is usually more common near woods. Controlling weeds and ensuring
good spray coverage improves control. |
