Please don't get me wrong.I am not complaining about insect noise. I am stating a fact that virgin forest such as 'Gunung Tahan'(In Malaysia) is also noisy at night. The noise does not come from insect, believe it come from wild animals like all kinds of monkey,wild birds,wild boar etc. In fact can hardly hear any insect noise as these were 'masked' by the sound of larger animals.
Just wondering, since you mention insect, will there be higher risk of mosquitoes' bites (may results in malaria/dengue) for those staying near hills/forests/jungle/park
