Hi, I didn't find this in my books, North Vietnam Thanks for tips Joachim I wonder if this is actually Cyclosia imitans female? The wing shape looks more like imitans than C. midamia. Adam. It could be a very dark form of C.imitans as the wings seem to look narrower than C.midamia. I just compared my specimen with one that Joachim posted.

livingplanet3 Cyclosia use HCN, which is highly toxic and volatile. This is how I was able to calculate what can happen. I don't know what Hypercompe uses but I guess it's just some distasteful liquid. My main experience with hydrogen cyanide is from the Cherry Laurel tree (Prunus caroliniana), which grows everywhere here in North Texas, and contains a large amount of this poison. When cut with a lawn mower, hedge trimmer, or any other means, they produce a very strong smell of almonds, which is the cyanide being released. I've cut down plenty of these "weed trees" over the years, but can't recall ever having had a reaction. I suppose that since it was outdoors, the vapors were able to disperse quickly enough.

Looking again, I noticed that Joachim seems to have taken the upperside photo at an angle from slightly below the specimen. That may create the illusion that the forewings are narrower than reality. Unfortunately I don't know how to distinguish the two species reliably. Perhaps someone here can let us know what easily visible characters are important. Adam.

Yes, the best think would be to place both species side by side to see if there is a difference.

Here are a couple of females of C. imitans from N. Thailand, also from Endo & Kishida (1999). Adam.
