Bog lygropia

Bog lygropia is a common, small to medium-sized, crambid snout moth. It occurs in the United States and southern Canada east of the Great Plains.

Adults are active from June through August. They are found in boggy and wet areas. They are commonly attracted to lights in residential areas. Larva host plants are unknown.

Adults have a ⅝″ to ⅞″ (17 to 22 mm) wingspan.

The wings are broad, and they are held spread out when at rest. The forewings are dull white to yellowish white. They are crossed with seven bold, dark brown to brownish-black lines, three in the basal area, two in the medial area, and two in the subterminal area. The lines branch and rejoin (anastomose), forming an intricate network and often oval or irregular patches of ground color. The fringe is checkered brown and white. The forewing markings are repeated on the hindwings, and the lines continue across the abdomen.

The antennae are long, slender and thread-like. The finger-like sensory organs (palps) attached to the mouth are upturned.
