Deuterophlebia shasta
Deuterophlebia shasta is a species of mountain midge in the family Deuterophlebiidae, first described by Wirth in 1951. This family represents one of the most primitive lineages of true flies (Diptera), with larvae that are highly specialized for life in cold, fast-flowing mountain streams. The species epithet 'shasta' refers to Mount Shasta in northern California, indicating the type locality. Deuterophlebiidae larvae are notable for their unusual body plan, featuring six pairs of ventral suckers that allow them to cling to rocks in torrential currents.
Hemileuca eglanterina shastaensis
Mount Shasta Sheep Moth
Hemileuca eglanterina shastaensis is a subspecies of sheep moth in the family Saturniidae, endemic to the Mount Shasta region of northern California. As a member of the Hemileuca genus, it is a day-flying moth with reduced mouthparts that does not feed as an adult. The subspecies exhibits the characteristic orange and black coloration typical of H. eglanterina, though with geographic variation associated with its isolated mountain habitat. Like other buck moths, its larvae possess urticating spines that can deliver painful stings.
