This alerts me a little, dear westowfish,because the site near Kota Tinggi I know and which I have visited four times already is on a sandy provisional road (that is in part like a dam leading through a residual peat swamp)and which can be referred to as a “mining road”. Lorrys go there all the time coming back loaded with sandy soil. Are-we talking about the same site? If so, I and others (such as Jit Sin and Zahar) have been collecting alfredis there which are, however, very hard to keeep in a state where they maintain red colors.But they are not difficult to breed. And there is no resemblance to nagys. But maybe you are talking about some other mining road. “On the way to Desaru” means coming from North? I would be eager to see your habitat pictures or can provide mine, which would go best through regular email, I presume.
