Image title | I have never seen Forest Tent Caterpillars, and this might be my last chance for ten years! So lucky to get a good shot of them :) Via Health Canada: Forest tent caterpillars feed on deciduous trees (trees that lose their leaves seasonally) in many parts of Canada . Outbreaks last two or more years and usually happen at intervals of ten years or more. They have a similar life cycle to the Eastern and Western tent caterpillars, with one distinct difference: instead of building tent-like webs, they make a type of silken mat on the trunk or branches where they collect to rest, leaving only to feed on the leaves. These caterpillars are a pale blue colour with black, and have a series of white spots on the back. The adult moth is a yellow-brown colour. |
