Your answer to the previous question was that your insect has wings that are all similar in structure.
Does your insect have mouthparts like a twisting or coiled tube; and wings that are covered with scales?
Look at the mouth of the insect for a straw-like tube that is either twisted or coiled up. (See the photo at right.)
In addition, use a magnifying glass, or preferably a microscope, to look for scales on its wings. (See the photo at right.) Scales are actually very small and overlapping pieces of a protein-containing material called chitin, which is the same material that is found in the insect’s exoskeleton.
These scales easily brush off the of insect, and look like dust, so be careful when handling your insect and don’t touch the wings with your fingers. The more scales it loses, the less colorful its wings will appear.
Click one of the following:
Yes, my insect has coiled or twisted, sucking mouthparts, and scale-covered wings.
No, my insect does not have these characteristics.
