Answer:
Explanation:
The family Cecidomyiidae in the order Diptera (flies) have many species that intergrade between gall making and leaf mining. The tulip spot gall, Thecodipolosis liriodendri, is only a slight thickening of the leaf while the tar-spot gall, produced by a species in the genus Asteriomyia has even less thickening and is little more than a leaf mine. The boxwood leaf miner, Monarthropalpus buxi, makes a leaf mine but the surrounding tissues proliferate.
