Chilo phragmitella is a species of moth of the family Crambidae, sometimes referred to by the vernacular names wainscot veneer[1] or reed veneer.[2] It was first described by Jacob Hübner between 1805 and 1810 as Tinea phragmitella, and is the type species of the genus Chilo.[3]

Chilo phragmitella occurs in wetland habitats with reed beds and paddy fields, and can be found in much of Europe, including Great-Britain, and parts of Asia.

Original description

Date of original description

The species was, as Tinea phragmitella,[4] first described by Jacob Hübner in his work Sammlung europäischer Schmetterlinge,[3] a multi-volume work with publication dates from 1793 to 1841.[5] Francis Hemming, in his 1937 systematic treatment[lower-alpha 1] of the entomological works of Jacob Hübner, narrowed the range of years in which the description of Tinea phragmitella may have been published to 18051810.[5]

Etymology

The specific name phragmitella refers to the species' larval food source.[6]

Distribution and habitat

Chilo phragmitella occurs in most of Europe,[4] including the British Isles.[7] It is also known from parts of Asia, including Iran,[8][9] Iraq,[9] Japan[9] and China.[9] It is found in wetlands with large reed beds[10] and paddy fields.[8]

Behaviour and appearance

Immature stages

Larvae are whitish and feed internally from stem and rootstock of common reed (Phragmites australis) and reed sweet-grass (Glyceria maxima).[7][11] Larvae take two years to mature.[12][13] Prior to pupation, the larva creates a hole in the stem to exit from as moth. Pupation occurs within the stem beneath the exit created by the larva.[7][14]

Adult

Adults are sexually dimorphic, with smaller, darker males. Wingspan is respectively 24–32 mm for males and 30–40 mm for females.[7] Both sexes have long labial palpi.[11] Female specimens of Chilo phragmitella may resemble those of Donacaula forficella.[6]

Depending on location, adults may be on wing from May to September. In Great-Britain, adults are on wing from June to July in a single generation.[7]

Handbook of British Lepidoptera

The following description of Chilo phragmitella was published in Edward Meyrick's 1895 A Handbook of British Lepidoptera:[15]

The face with a conical horny projection. The labial palpi longer than head and thorax. Forewings in female much narrower and more acute than in male ; pale ochreous, more or less suffused with brown, especially in male, tending to form dark streaks on and between veins ; a dark fuscous discal dot ; termen sinuate. Hindwings are pale whitish-ochreous or whitish, The larva is ochreous -whitish ; dorsal, subdorsal, and lateral lines reddish -brown ; head and plate of 2 yellowish -brown.
