Does your insect have a fairly long thorax , two small cerci at the end of its abdomen, and smoky-colored wings?
Look for the cerci at the tip of the abdomen. In some insects with this feature, one cerci may be a bit larger and/or may have a different shape than the other.
Check the length og hte thorax. Since each pair of legs arise from one segment of the three-segmented thorax, the legs will also be a distance from one another.
Click one of the following:
