Bristly Cutworm Moth

Fascinating facts about the Bristly Cutworm Moth

• The bristly cutworm moth has a wingspan of just 21-30 mm, which is markedly smaller than the majority of its Noctuidae relatives. This compact measurement places it among the tiniest members of the family, whose species often exceed that range. Its diminutive size is evident when the moth is observed perched, making it easy to separate from larger noctuids. Such a small wingspan influences how it manoeuvres through low vegetation.
• When settled, the adult folds its hindwings tightly beneath the forewings, producing an arrowhead-like or tented outline. This posture creates a distinctive silhouette that stands out against the foliage where the moth rests. Observers can spot the shape even without close inspection, as the tucked wings give the moth a characteristic profile. The habit is a reliable field cue for identifying Lacinipolia renigera.
• The forewings display a dark greyish-brown background punctuated by three green spots, one of which is outlined in white. These markings form a striking trio that contrasts sharply with the muted wing colour. Alongside the forewing pattern, the hindwing fades from whitish-gray to a darker margin, enhancing the overall appearance. Together the colour pattern provides a dependable visual marker for the species.
• Adults are on the wing from May through October, but the exact timing shifts with latitude. In the southern part of its range they can be seen as early as May, while northern populations often do not appear until mid-summer. The moth is endemic to most of North America, absent only from Yukon, Alaska and the Gulf coastal plain, so regional climate dictates the start and end of its flight period.
• The larvae feed on a wide variety of herbaceous plants such as chicory, dandelions and clovers, exploiting many common garden and field species. They also attack cultivated crops, being recorded as pests of cabbage, lettuce and corn, which can lead to noticeable damage in agricultural settings. Because these food plants are abundant across its North American range, the caterpillars can thrive in both wild and farmed habitats.
