Damage to trees is relatively low except in
extreme cases, however the irritating nature of larval hairs may cause problems to the
public. Hairs may become detached from the larvae and be translocated by wind.
Skin reactions due to allergic sensitivity are not uncommon. |

Complete metamorphosis life cycle. This
moth is of relatively large body size (Macro Lepidoptera). Adults are usually on the
wing in high summer. Eggs are laid in batches, usually at the stem of the host
plant, and covered with (allergenic) hairs. Larvae spin silken tents from which they
forage. |

Cutting and burning of winter tents between
November and march is recommended. If the use
of insecticides is deemed necessary, application in mid May or mid September is most
effective. Consult applicable regional law for approved pesticides. |
