This record describes Phycitodes binaevella (species). Recorded family: Pyralidae. Recorded order: Lepidoptera.

Identification and Appearance

Phycitodes binaevella - Phycitodes binaevella

Wingspan 22-27 mm. The easiest of the three British species of Phycitodes to identify; it is the largest and has large blackish dots on a paler ground colour. The resting posture where the wings are rolled tightly around the body is common to the group. Favouring areas where the larval food plant is present. The single generation flies in July and August. The larvae feed inside the flower heads of Spear Thistle It occurs fairly frequently throughout England and Ireland. In the Butterfly Conservation’s Microlepidoptera Report 2011 this species was classified as common.

About Butterflies and Moths: the wider group

Order-level background for Lepidoptera, the group containing Phycitodes binaevella. Species-specific details appear above.

Group overview

Lepidoptera includes approximately 180,000 described species of butterflies and moths. Moths outnumber butterflies roughly 10:1. The monarch butterfly's eastern population has declined by more than 80% since the mid-1990s, and the western population by over 95% since the 1980s. The IUCN lists the migratory monarch as Vulnerable.

Ecological role of the group

Butterflies and moths are essential indicators of ecosystem health. As caterpillars, they are a primary food source for birds - a single nest of blue tit chicks requires ~10,000 caterpillars. Adult moths pollinate many night-blooming plants.

Economic and practical significance of the group

Lepidoptera are critical pollinators. In Europe, grassland butterfly species have declined by almost 50% since the early 1990s. In the UK, three-quarters of butterflies are in decline. In the U.S., five butterfly species have gone extinct since 1950, with 29 listed as endangered.
