- The lowest level of the atmosphere is the troposphere.
- This layer is where all the bulk of the atmospheric gases are domiciled.
- Weather conditions occur here.
- This layer is not safe for flight due to its turbulent nature.
- The ionosphere is responsible for the transmission of radio signals around the earth.
- The earth's weather occurs in the region of the troposphere.
Adults of species in the order <u>Coleoptera</u> have 2 wings and the greatest variety of mouthparts.
<h3>Order Coleoptera</h3>
The coleopterans, (order Coleoptera), consist of the beetles and weevils. It is the largest order of insects.
They have two pairs of wings:
- One of the pair is the hard-shelled outer wings known as the “elytra”. These are not used for flying, but to protect the beetle's flying set of wings and its body as it crawls through narrow passages and tunnels in a tree.
- The second set of wings is membranous and is folded under the elytra when not in use.
