Anacampsis populella is a moth of the family Gelechiidae, which is native to Europe and has been accidentally introduced to North America. It was first described in 1759 by Carl Alexander Clerck, a Swedish entomologist. The type specimen is from Sweden. The foodplants of the larvae are poplars (Populus species) and willows (Salix species).




Life cycle



The wingspan is 14–19 mm, the colours are variable and the sexes are similar. Abdomen with segments 2-4 often ochreous-yellow. Forewings are whitish, more or less irrorated with black or dark grey, usually palest towards base of costa; costal edge sometimes yellowish-tinged; sometimes a large black patch occupying dorsal 2/3 from base to near tornus stigmata blackish, often concealed ; a whitish obtusely angulated fascia at 3/4 , indented above angle, sometimes indistinct terminal black dots. Hindwings over 1, rather dark grey. The larva is pale grey-greenish or yellowish ; dots black ; head and plate of 2 black.
They are on wing from June to September, depending on the location, and can be found on tree trunks, dislodged from foliage or swept from creeping willow (Salix repens). They also come to light. A similar species, A. blattariella is also a variable species and can only be told apart from A. populella by genitalia dissection.




= Ovum

=
Eggs are laid on various species of poplar including aspen (Populus tremula) and willows, such as goat willow (Salix caprea) and white willow (Salix alba).




= Larva

=

Larvae can be found from mid-April to June. The head and divided prothoracic plate are black and the body is greyish green with round black pinacula which are easily seen, while the anal plate is brownish. The larva rolls a leaf into a tube, held together with silken strands which can be seen on the edges of the roll. On creeping willow, due to their small size several leaves are spun around the central shoot, starting a short distance below the tip and working upwards. Larvae of A. temerella also roll leaves around creeping willow.




= Pupa

=
Pupation takes place in a cocoon within a rolled leaf of the foodplant.




Distribution


The moth is found in most of Europe and has been accidentally introduced to North America.
