Crickets are one of the insects with strigils (yea, sorry about stridulator - shouldn't it be stridulation organ?). I made photos of their wings - with help of microscope and I can see there sth what looks like a comb. I only want to know if it is it. Photos are not good but the main string you can see on them looks a little bit like a comb.
