tracheole (plural tracheoles)

1. One of the fine branching tubes of the trachea of an insect, which penetrates the tissues to provide oxygen.
   • 1886, Frank Richard Cheshire, Bees & Bee-keeping, page 42:

     Indeed, in the muscles of the wings every fibre has its own particular tracheole (small trachea).

   • 1920, John Henry Comstock, An Introduction to Entomology, page 118:

     A subsequent molting of the intima of the trachea opens a connection between the lumen of the tracheole and the trachea. At the same time or a little later the tracheole breaks forth from its mother cell, uncoils, and extends far beyond the cell in which it was developed.

   • 2002, Wilfried Wichard, Biological Atlas of Aquatic Insects, page 86:

     Oxygen is absorbed all over the body surface through branched tracheoles which are located directly under the body surface.
