|scientific name Argyrotaenia pinatubana |
common name Pine-tube Moth
Coniferous and mixed forest.
Late April to early June (Freeman 1958).
The forewing is shiny light yellow with some brown reticulation. Broad brown bands that slant towards the anal angle dominate the wing in the basal, median, and upper postmedian areas. The head and thorax are brown while the abdomen and hindwings are medium grey.
The larva is dull yellow with slightly darker brownish yellow thoracic shield and head.
The solitary larva starts as a needle miner in early instars (MacKay 1962). In later instars they live inside a tube made form several needles tied together, gradually feeding on the end of it. As tubes get short from larval feeding, they are abandoned to construct newer ones which are also where pupation occurs (Forbes 1923).
Not of concern but rare in Alberta.
The larva is found most commonly on White Pine (Pinus strobus) in eastern Canada, it is rarer in the west on other species of pine.
From British Columbia to Nova Scotia, south in the east to Florida, in Alberta it is sporadically encountered in the boreal.
