Records in world of insects

[Prirodoslovni muzej Split]

Dear Friends, 
I am interested in interesting details about insects: the smallest, the biggest, the fastest, the most poisonous, 
the best jumper, swimmer and so on... This topic is interesting for me to know and I need it  for my insect exhibition especially.
Do you know how many people died of plague transferred by flea in Middle Ages or how many dollars are spent per year against pests to protect plants? 

Thanks in advance!
