Pink Underwing
catocala concumbens
The Pink Underwing (Catocala concumbens) is a captivating member of the Erebidae family, renowned for its dramatic defense mechanism. By day, this moth rests quietly on the bark of willow and poplar trees, perfectly camouflaged. Its forewings present a delicate mosaic of soft gray, white, and charcoal, blending seamlessly with lichen-covered trunks. However, if a predator gets too close, the Pink Underwing flashes its hindwings, revealing a striking, brilliant pink coloration bordered by deep black. This sudden burst of color startles predators, giving the moth a crucial split-second to escape. Found predominantly in riparian corridors, woodlands, and suburban areas across eastern North America, this species is a favorite among moth enthusiasts. Its life cycle is intimately tied to willow and poplar trees, where the larvae feed before pupating into these exquisite adult specimens.
Lebensraum: Found in damp woodlands, river valleys, and suburban areas rich in willow and poplar trees.
Aussehen
The Pink Underwing is a medium-to-large moth with a wingspan ranging from 6 to 8 centimeters. Its closed forewings are characterized by a highly cryptic, pale gray or silvery-white coloration adorned with dark, jagged zig-zag lines that perfectly mimic tree bark. In stark contrast, the hindwings are a vivid, bright rosy-pink with a thick black band running parallel to the edge and a clean white fringe along the margin. Its body is robust and covered in dense, fuzzy gray hairs, while its underside shows a contrasting pattern of black and white bands.

Interessante Fakten
The scientific species name concumbens translates from Latin to lying together, likely referring to how flatly the wings are held against tree trunks during rest.
To study this species, entomologists paint a sweet, fermented mixture of beer, molasses, and bananas onto tree trunks to lure the moths at night.
While resting, its bark-like forewings provide such perfect camouflage that the moth can remain completely undetected by predators in broad daylight.
