Thank you Phil,

I cannot see the male or female appendages on the pictures . Even when I have them at hand, it is difficult to see because the furry spines hide the details. I found some males but only after damaging the specimens. The easiest way for me - so far - is to put a bunch of dead specimens in warm 10% KOH for a couple of minutes, which also makes the scales detach. The males I found so far seem smaller than the females.

I have another problem with the so-called ascoids, filamentous organs on each of the antennal segments. I cannot distinguish them from the numerous setae that form a whirl around each segment! Is there a method to make the ascoids visible?

Thanks in advance, Louis
