Crambus hamella
species of insect
Crambus hamella is a species of moth in the family Crambidae described by Carl Peter Thunberg in 1788. It is found in most of Europe (except the Iberian Peninsula and most of the Balkan Peninsula), east to the Russian Far East (Amur, Sakhalin) and Japan. It is also found in North America, including Alberta, Arizona, Manitoba, Michigan, Oklahoma and Ontario.
The wingspan is 18–23 mm. The forewings with apex slightly produced; brown, posteriorly whitish-sprinkled, terminally suffused with white; a broad snow - white pointed median longitudinal streak from base, not reaching second line, lower edge with a projection in middle; second line angulated, silvery - white, anteriorly dark-edged; a triangular white subapical spot; several terminal longitudinal black marks; cilia metallic. Hindwings are grey. See also Parsons et al.
Adults are on wing from July to August in generation per year.
The larvae feed on grasses, possibly including Deschampsia flexuosa.

Why this record matters
“Crambus hamella” is worth following because a concise public description often conceals a longer documentary argument. Here, Crambus, hamella and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q4036632. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1788.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
