Dear all,

Is it possible to separate Culex from Aedes based in differences in R2 and R2+3 length? I've read that in Culex the R2 is larger than the size of R2+3 (A and B in figure), and that in Aedes is the opposite (C and D in figure). My specimens are from southern Brazil, and as a herpetologist I'm just trying to have a first identification of genera... within Culicinae, my main interest is to diagnose Culex. Images are not at scale, ignore the values.

Thanks
