Baltimore Snout

Fascinating facts about the Baltimore Snout

• The Baltimore hypena measures between 26 and 32 mm across its wings, a modest size for a moth. When it settles it folds its hindwings tightly beneath the forewings, a habit that produces a clean, triangular outline. Its forewings are a muted gray-brown, and females often show a slightly lighter hue that males lack. This compact posture helps it blend into bark and leaves while at rest.
• A prominent dark patch dominates most of the outer portion of each forewing, stretching to roughly three-quarters of the wing length before stopping short of the inner edge. The remaining inner margins and lower wing areas are mottled in grey-brown, crossed by a dark diagonal line that runs inward from each corner. This pattern is especially noticeable on females, adding contrast that may break up the moth's outline on tree bark.
• Adult Baltimore hypenas are active from early spring through late autumn, with flight periods ranging from April to October depending on regional climate. In cooler northern areas they appear later and disappear sooner, while warmer southern locales extend their season. Throughout this time they are most frequently encountered in or near deciduous forests, where suitable host maples are abundant for their larvae.
• In New England the Baltimore hypena manages at least two full breeding cycles each year, with eggs hatching, larvae feeding and adults emerging again before autumn. Further south the warmer climate allows the species to squeeze in extra generations beyond the two, extending its reproductive period. Because adults are on wing from April through October, the later-season flights provide the opportunity for these additional broods.
• Caterpillars of the Baltimore hypena rely on maple trees for food, preferring red and silver maple as their primary hosts. The larvae consume the leaves of these maples, which are abundant in the moth's preferred habitat. Consequently the species is most often encountered in or near deciduous forests where such maples thrive, ensuring a ready supply of nourishment for the young.
