Noun

pterostigma (plural pterostigmata)

1. (zoology) A spot on the outer wing of insects which is often thickened or coloured and so stands out from the rest; it is a group of specialized cells and has an effect on flight dynamics.

   Coordinate term: pseudopterostigma (looks similar but has different structure and function)
