Some of the spawn points for bugs show the one type of bug but when catching it it notify and show in inventory another type of insect. The first time I noticed it I was catching only bees, queen bees, grasshoppers and fly's. When I got to sell I found 3 insects in my inventory I am sure I was not hunting. On youtube I saw a youtuber mentioning the same thing and so I went back and took careful notice chasing bugs on what I had in my sights and what I caught. There was a fly before me , but after I caught it it said I caught a grasshopper and so it showed in my inventory.
