The insects in Madeira which are not ground-feeders, and which, as certain flower-feeding coleoptera and lepidoptera, must habitually use their wings to gain their subsistence, have, as Mr. Wollaston suspects, their wings not at all reduced, but even enlarged.

马德拉昆虫不是地面食性动， 像某些以花为食鞘目和鳞目昆虫，必须习惯性地使用膀来维持生计， 正如沃拉斯顿先生所怀疑那样， 膀根本没有减少， 但甚至扩大。
