Gasteracantha dalyi, Long Horned Spiny Spider

Really amazing insect ever had seen in my life, this spider usually seen in thick and deciduous forest range which are very clumpy and the sign we observe where the lack of ornitho's (Birds) grazing, When the hunt initiated, that time these orb veawer spider will create the clumpy web immediately, some other insects trapping birds will find the orbs by their own signals. We observed one interesting fact on this spider, which behavior is almost like human, that is silent preying aim. Some specific forest is the shelter of this spider. Have specific climate condition even.
