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.
Madeirako intsektuek, ez baitute jatekoa lurrean aurkitzen eta, zenbait koleoptero eta lepidoptero lorajalek bezala, beren mantenua bilatzeko hegoak erabili beharra baitute, hegoak, Wollaston jaunak susmatzen duen moduan, txikiagoturik barik agian handiagoturik dituzte. Hau erabat bateragarria da hautespen naturalaren ihardunarekin.
