Abstract

This report is a result of observations made while doing laboratory exercises on external insect morphology. In working with the Mullein Thrips it was found quite difficult to spread the wings perpendicular to the body for study. Close observation under high power of a binocular microscope revealed that the hairs of the wings were held in the resting position by two small hooks on each side of each abdominal tergite except on segments one, eight, nine and ten. When the bodies of the thrips were cleared by boiling them in a five percent solution of potassium hydroxide for one hour the hooks could be seen quite easily.
