A KEY TO THE
"BIG TEN"
INSECT ORDERS

Leaf-footed Bug, family CoreidaeSee if you can "key out" the insect at the left. Note that the wings on the insect's right are forced open. When this species is at rest, its back wings are hidden beneath its front wings. Also, you can't see the mouth parts, but they are of the "sucking" type.

HOW THE KEY WORKS:
Note that you have two sections begining with the number 1. Which #1 describes the insect? Is the insect best described in the first option 1 (Wings absent or... ) or the second option 1 (Wings clearly visible)? If the first option 1 best describes your insect, then drop down to the two option 7s. If the second option 1 is best, drop down to the two option 2s. Keep doing this until an option description leads to a name, not another number.

Wings absent or if present hidden beneath thick, sometimes hard and shiny, sometimes leathery, front wings, or wing coverings (Be careful here. If there's a crack down the back, probably that's where the front wings or wing coverings meet and there are regular flying wings folded below...) Go to...

OK, the test insect is a Hemiptera, a "true bug." It's a Leaf-footed Bug of the family Coreidae, but I'm not sure what its genus and species are.
