977 Large Fruit-tree Tortrix Archips podana
(Scopoli, 1763)Wingspan 18-26 mm.
Archips podana is quite common in low-lying areas throughout England and Wales, but less so in Scotland.
Sexual dimorphism is quite pronounced. The male has a costal fold on the forewing, and is usually smaller and more brightly coloured than the female. The female has no costal fold, and a much more protruding apex on the forewing.
The main flight period is June - July, but adults can be found from May to September, late emerging specimens possibly being a less numerous second generation. They come readily to light.
The larvae feed on the foliage, flowers and fruit of a wide variety of deciduous trees, including apple (Malus), plum, sloe and cherry (Prunus spp.) and, occasionally, conifers. The usual larval development is to feed July – September, and, after overwintering, to complete feeding and growth in the following April – May. But sometimes, full-grown larvae can be found in late August, which pupate and emerge as adults in early September. Final instar larvae usually have brown heads and prothoracic plates, but black also occurs. Archips xylosteana and A. rosana have similar larvae.
