Even if hypno-net may be lethal most of the danger come by looking them ... or if you avoid looking to stumble inside one
But the spider is the real problem at soon you concentrate on the hypno-net to avoid it, the highly poisonous and mimetic Rainbow spider will attack you from behind your visual field.

Luckily the Rainbow Spider are very emphatic and will never harm you if you act friendly and you have some fry flies to offer.
(Rainbow Spider are greedy for fry flies and even mosquitos, better if with no ketchup and much larvae sauce . )
