What does a hemipterologist collect?

The hemipterology is the branch of entomology that studies the order Hemiptera, including bedbugs, squashbugs, and aphids. The Hemiptera or true bugs are an order of insects comprising some 50,000 to 80,000 species of groups such as the cicadas, aphids, planthoppers, leafhoppers, and shield bugs. The name "true bugs" is sometimes limited to the suborder Heteroptera.
