Thysanoptera \Thy`sa*nop"te*ra\, n. pl. [NL., from Gr. ? a
fringe + ? a wing.] (Zool.)
A division of insects, considered by some writers a distinct
order, but regarded by others as belonging to the Hemiptera.
They are all of small size, and have narrow, broadly fringed
wings with rudimentary nervures. Most of the species feed
upon the juices of plants, and some, as those which attack
grain, are very injurious to crops. Called also {Physopoda}.
See {Thrips}.
