common white wave

<em>Cabera pusaria</em>, commonly known as the common white wave, is a moth in the family Geometridae, distributed across temperate Europe with confirmed occurrences in Belgium, Denmark, Norway, and Sweden. It is classified as Least Concern by the IUCN, indicating stable populations with no significant conservation concerns at present. The species is closely associated with deciduous woodland habitats, particularly areas dominated by birch, alder, and poplar, which serve as primary larval host plants. Adults are white to pale gray with fine, darker wavy cross-lines on the wings, providing effective camouflage against pale bark and lichen-covered surfaces when at rest. <em>Cabera pusaria</em> is superficially similar to its congener <em>Cabera exanthemata</em>, the common wave, and the two species often occur together in the same woodland habitats. Adults typically fly in two generations per year, from late spring through early summer and again in late summer. The species is primarily nocturnal and is attracted to artificial light, making it a regular component of moth trap catches across its range. Biological traits including average adult lifespan, wingspan measurements, and body mass remain poorly documented in standardized databases. Ecologically, the common white wave participates in woodland food webs as a larval foliage feeder and as a prey item for insectivorous bats and birds throughout its temperate European distribution range.
