Familiarize yourself with PEP8 for naming and coding-conventions first.

Depending on what the Type is, you might consider using subclassing here 
instead.

Instead of manually coding attributes for all kinds of insects, better 
use a mapping of insect-name to attributes. There are plenty of options 
for that - you could a mapping of name to tuple:

{ "cockroach" : (100, 200),
   "wasp" : (2000, 3000)
}

Or introduce a InsectInfo-class that has finds and numbers as fields:

{ "bee" : InsectInfo(finds=100, number=200) }
