Insect Scorpion

This little insect is too small to be seen clearly with unaided eyes. It looks black in colour and it randomly bit me, it’s bite is just like a sting of a mosquito. I don’t know what it’s called hence, I name this little insect ‘Insect Scorpion’.

Pollens of unidentified tree

Noticed a strange flower in TISS campus, tried to find its name but couldn’t. Can someone help me identify it? Photographed its pollens with d Foldscope, they look beautiful! Pollen size is ~60 microns. Need help in identifying name of plant.
