Cricket Dissection
Here, the cricket's crop and digestive system have been pulled free and placed towards the bottom of the image so you can see what's underneath. In the thorax, it's the flight muscles. In the abdomen, there isn't much to see at the moment, but if this cricket were slightly older, the ovaries would be highly visible. Instead, most of what's left in the abdomen is fat - part of the fat body - and tracheoles, hollow tubes that run throughout an insect's body and allow it to breathe. Insects don't use fat in quite the same way that humans do. As a whole, an insect's "fat body" acts very much like a human's liver. It's an organ for storing and processing resources, and is very metabolically active.
