The case of this insect is long and thin, and covered with finely chewed lichen. It is unclear at this stage if it is actually a Psychidae larva. It has a length of about 3 cms.

The long one pictured here was on a Red Cedar tree trunk, apparently feeding on

  • Lichens.

    Typically it was anchored at one end that stayed anchored, and was eating the lichens in a pattern like a windscreen wiper. So one day it was horizontal say 3 o'clock, the next day it was up a little say 1.30, and the next day it was vertical at 12 o'clock, the next day it was 10.30, and then next dayat 9 o'clock.
