“ The name “palmer” or “palmer-worm” is often given to many kinds of hairy caterpillars, specifically to that of the destructive tineid moth, Ypsilophus pometella. The name is either due to the English use of “palm” for the blossom or catkin of the willow-tree, to which the caterpillars bear some resemblance, or to the wandering pilgrim-like habits of such caterpillars. Artificial flies used in angling, covered with bristling hairs, are known also as “palmers” or “hackles.” ”
