323. Sharp-lined Yellow

This is a very attractive small moth is attracted to the lights on our porch on summer evenings.  The yellow colour is easily mistaken on a branch for a yellowed and wilted leaf.   It has a variety of english names, including the Pink-bordered Yellow and the Two-pronged Looper.  The latter is from the two spikes on the caterpillar, which adds to its effectiveness as a accomplished twig mimic.

Sicya macularia caterpillars feed on a variety of deciduous shrubs including alder, blueberry, buckthorn, currant, false azalea, poplar, shrubby cinquefoil, spiraea, and  willow.
