Silver-Spotted Tiger Moth

Fascinating facts about the Silver-Spotted Tiger Moth

• The young caterpillars are brown or reddish-brown and covered in dense hair, especially bundles of black and yellow hairs along their backs. These hairs are not just decorative; they can cause irritation if they touch human skin. The same irritating hairs are present on the pupae, extending the defensive trait into the next life stage. This means handling the larvae or their cocoons may result in a painful skin reaction.
• Silver-spotted tiger moths complete a single generation each year. In mid-summer the adults deposit clusters of eggs on pine needles and small branches of their host trees. Those eggs hatch after roughly three weeks, releasing larvae that will soon begin feeding. This timing ensures the larvae emerge when fresh foliage is abundant for growth.
• After hatching, groups of larvae spin communal silk tents on the needles of their host conifers and stay inside throughout the winter months. When spring arrives they abandon the tents and each caterpillar feeds alone on the foliage. Later in the season, each larva pupates in a brown cocoon that it attaches to a plant or drops to the forest floor. This seasonal shift from group shelter to solitary feeding prepares them for successful metamorphosis.
• Adult silver-spotted tiger moths have brown forewings marked with irregular silvery spots that are each outlined in black and arranged in loose rows. The spots vary in size, with the costal spot being the largest and the marginal row uniformly round.
• The silver-spotted tiger moth inhabits a broad swath of western North America, ranging from British Columbia down to southern California and extending eastward through Arizona, Nevada, New Mexico, Colorado, Utah, Wyoming and possibly into northern Mexico. Within this range it occupies both coastal forests and the Rocky Mountain region, where the subspecies L. subalpina is found. The species also includes a Californian subspecies, L.
