FAQ
Frequently Asked Questions

The adult resembles a small, stocky wasp but is harmless to humans. The larvae look like caterpillars (but have more than five pairs of prolegs) and are often green or brown, feeding in groups on spruce needles.
It can be very serious in forestry. Severe defoliation for consecutive years can stunt growth, kill branches, or even kill mature trees, leading to significant economic loss and ecosystem changes.
Yes, ornamental spruce trees are also susceptible. Look for groups of caterpillar-like larvae and chewed needles, typically in late spring or summer. Physical removal or approved insecticides can manage small-scale infestations.
