Does anyone know how to keep the wings of alcohol preserved specimens from curling when drying?

Sigara sp.
Speciose genus...may be difficult to figure out without male specimens; males can be distinguished from females by the palar pegs on the palae (front tarsi), asymmetrical dorsal terminalia, and the strigil- see my recent submission of a male S. omani for more info. Beyond that you need a good reference- Hungerford's the best but it's difficult to obtain and may be difficult to use; even better would be a regional key to narrow down the choices.

I have the same problem of wing curling with alcoholed specimens and have not been able to solve it. Recently I've started doing my corixid species IDs in alcohol/pliable state before mounting them. Specimens are easier to manipulate without breaking them.

 
Thanks Tim
I found the Hungerford paper online here, but unfortunately I can't download as pdf, only browse.

I'll have to look to see if I have any male specimens.
