A very worn Statherotis discana

Tortricidae, Olethreutinae

Note that the very similar S. leucaspis has not yet been recorded from Hong Kong. The females of S. discana and S. leucaspis are not possible to tell apart on external features; the males are separated by the presence in S. discana of a large patch of raised black scent scales on the dorsal surface of the hindwing. All males found so far have been S. discana. Consequently, please also note my thesis should be updated as I identified S. discana incorrectly at the time and place it as S. leucaspis.

cheers,

Roger.

Thank you Roger.
Here is a similar one but much smaller. Are they the same?

This also looks like Statherotis discana.

cheers,

Roger.

All the Statherotis specimens I've checked for HK are S. discana. Statherotis leucaspis might aslo occur in HK, but no records yet.
Males of discana have a jet black scent patch submedially on the dorsal side of the hindwing.

Please update your e-copy of my thesis accordingly!

cheers,  Roger.

without checking to see if it's a male with a black scent patch in the middle of the hindwing, it's very difficult to be 100% sure this is S. discana rather than S. leucaspis. However, all the specimens I've checked in HK have been discana, so in all probability this is S. discana

Having said that, S*d's Law states that the next one I check will be S. leucaspis!

cheers,  Roger.

作者: Shirley    時間: 2013-9-9 21:10     標題: Statherotis discana?

My suggestion is Tortricidae, Olethreutinae: Statherotis discana

OPen to correction as always.

Thanks

Andrew

Agree.
作者: hkmoths    時間: 2013-9-11 10:32

looks like it has ceased to be S. dicana - breathed its last already.
