Tortrix moths -
The family Tortricinae includes a large Genus -
Acleris cristana and Acleris hastiana
Both have very variable wing colours and patterns.
A.cristana often has a white head and/or a brightly coloured S-
Very large scale tuft in the centre of the forewing.
A number of scale tufts but they are smaller.
Leading edge of the forewing curves inwards strongly.
Leading edge of the forewing is straighter than in A.cristana
Acleris variegana -
The half of the forewing near the base is often white.
There are large scale clusters in the middle of the white patch.
There are also small scale clusters round the edge of the patch.
The other half of the forewing is various colours -
Sometimes the half of the forewing near the base of A.variegana is not all white, but a patch around the large scale tufts is coloured.
There are sometimes specimens of A.variegana where the basal half of the wing is not white but is near to the background colour and difficult to see as different.
Acleris ferrugana and Acleris notana
It is generally accepted that these two species cannot easily be separated by wing colours and patterns. Both species are very variable in colour and patterns. They will either have to be killed and dissected or recorded as Acleris ferrugana/notana agg.
Usually a scale tuft in the centre of the forewing.
Large hollow triangular mark extending from the leading edge of the forewing. The
mark is usually blotchy -
Small scale tuft a quarter of the way down the forewing indicates this is probably A.ferrugana
Acleris comoriana and Acleris laterana
A.comoriana and A.laterana cannot usually be separated just by looking at photographs.
Acleris ferrugana/notana agg.
Acleris laterana/comoriana agg.
Triangular mark solid, rounded and often red -
Rhomboid Tortrix Acleris rhombana
Hook effect at the wing tip
The wing markings are consistent but sometimes there is an area of dark colour obscuring the centre of the wing.
Acleris forsskaleana has
much wider wings than other Acleris species with a net pattern such as A.rhombana
Check also Aleimma loeflingiana and Pandemis corylana
Variable in wing patterns but usually netted.
Background colour of the forewing is golden brown with usually a light net pattern.
Large triangular mark extending from the leading edge of the forewing usually has a projection towards the trailing edge.
A.laterana (Wing length 7-
A.laterana has a shorter flight period. An adult moth seen in early June or November could be assumed to be A.comoriana
