Elachista utonella is a moth of the family Elachistidae found in Asia and Europe.
Description
[edit ]The wingspan is 8–9 millimetres (0.31–0.35 in).[1] The head is grey in the male, whitish in the female.Forewings are rather dark fuscous or ochreous-grey, pale-sprinkled, lighter in female; plical stigma elongate, black, preceded and followed by whitish marks; a small tornal spot, and larger triangular anteriorly dark-edged opposite costal spot white.Hindwings are dark grey.The larva is grey; head brown; 2 pale yellowish, with two brown spots.[2] [3] [4] Dissection is necessary to separate the moth from the similar Elachista albidella and Elachista eleochariella .[5]
There is one generation per year in Great Britain, but there are possibly two generations in continental Europe. The larvae feed on lesser pond-sedge (Carex acutiformis ), Carex brizoides , distant sedge (Carex distans ), brown sedge (Carex disticha ), star sedge (Carex echinata ), Carex elata , glaucous sedge (Carex flacca ), hairy sedge (Carex hirta ), Carex muricata , greater tussock-sedge (Carex paniculata ), Carex remota , greater pond sedge (Carex riparia ), spiked sedge (Carex spicata ), bladder sedge (Carex vesicaria ), fescue (Festuca species), saltmarsh rush (Juncus gerardii ) and Scirus sylvaticus . They mine the leaves of their host plant.[6]
Distribution
[edit ]Elachista utonella is found from Fennoscandia to the Pyrenees and Italy and from Ireland to Romania.[7] It is also found in the Russian Far East and Japan.
