1647. Moths (Phalï¾µnï¾µ L.) constitute the third, and by far the most numerous, division of lepidopterous insects; and it is among these we find the greatest proportion of injurious and destructive species. Nearly all, in their larva or caterpillar state, are external feeders; that is, they feed upon leaves: on changing into the chrysalis state, they either conceal themselves within a silken cocoon, or burrow in the earth; but are never exposed like butterflies. The perfect insects seek their food during the night, generally beginning their flight in the dusk of the evening. The antennï¾µ are thickest at the base, and gradually become more slender, until they terminate in a fine point: but some have their antennï¾µ feathered. Many hundred species of moths inhabit Britain, and thousands are already known as natives of foreign countries.
