Description
Phycita roborella is a species of snout moth (family Pyralidae). The adult moth has a wingspan ranging from 20 to 26 mm. The forewings are generally brownish‑grey with variable darker markings and a subtle longitudinal pattern; hindwings are paler, often light grey. The species exhibits the typical resting posture of Phycitinae, with wings held roof‑like over the body.
Distribution and Habitat
The species is native to Europe, with records spanning from the British Isles and the Iberian Peninsula in the west, through central Europe (e.g., Germany, Poland, Czech Republic), to the Baltic states and parts of northern Scandinavia. It inhabits deciduous woodlands, especially those dominated by oak (Quercus spp.), as well as parklands and hedgerows where host plants occur.
Biology and Ecology
- Flight period: Adults are on the wing primarily from June to August, though local phenology may shift by one month in southern or northern extremes of the range.
- Larval host plants: The larvae feed on the foliage of oak trees (Quercus spp.). Feeding is typically external on the leaves, creating small holes or mines, and larvae are known to overwinter in a cocoon or within leaf litter.
- Life cycle: The species is univoltine (one generation per year) in most of its range. Eggs are laid on host plant leaves; larvae develop through several instars before pupating in a loosely spun cocoon among leaf debris or in the soil.
Conservation Status
Phycita roborella is not listed as threatened on a European scale and is generally considered common within suitable habitats. No specific conservation measures are recorded for this species.
