Thread subject: Diptera.info :: Sexual dimorphism of Gampsocera numerata

Hello,

I came across Chloropidae Gampsocera numerata. The male has large black patterns on their wings, female not.

Are there other examples where wings of male/female heavily differ.

There are papers showing the the veins differ slightly: e.g. https://bmcecolevol.biomedcentral.com/articles/10.1186/1471-2148-9-110

But are there other examples, where black patterns are present/absent in male/female wings.

Regards

Lothar

The most common fly you will see is Drosophila suzukii. The male has a black spot near the wingtip. The female wing is clear. This species is in the species group discussed in the paper you linked.

I think only males of some Sphenometopa have wing spots.

Many species have sexual dimorphism in pattern or intensity, for example most of genus Chrysops and one of the European Rivellia.
