Anacampsis populella

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. 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.[2][3]

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).[2]

Larva
Rolled leaf in which the larva feeds

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.[2][3] Larvae of A. temerella also roll leaves around creeping willow.[4]

Pupa

Pupation takes place in a cocoon within a rolled leaf of the foodplant.[2]

Distribution

The moth is found in most of Europe and has been accidentally introduced to North America.[2]
