Meanings

1. One of the fine branching tubes of the trachea of an insect, which penetrates the tissues to provide oxygen.
   • Oxygen is absorbed all over the body surface through branched tracheoles which are located directly under the body surface. 2002, Wilfried Wichard, Biological Atlas of Aquatic Insects, page 86:
   • Indeed, in the muscles of the wings every fibre has its own particular tracheole (small trachea). 1886, Frank Richard Cheshire, Bees & Bee-keeping, page 42:
   • 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. 1920, John Henry Comstock, An Introduction to Entomology, page 118:
