the railway-bank and the down; often seen toying with a breeze-rocked flower as yellow-coated as himself, as though he had mistaken it, in its fluttering, for one of his mates.
Then the Peacock and Red Admiral are attached to several plants of the composite order, such as the thistles, teazle, and above all (as far as I have observed), to that fine, stalwart plant that frequently abounds in thickets, &c., and known as Hemp Agrimony (Eupatorium cannabinum). I seldom, at the proper season, visit a clump of this growing in a sunny opening, without finding, besides a store of other insects, one or both of these grand butterflies enthroned on the ample purplish flower-heads, and fanning their gorgeous wings, after the custom of their genus, then launching into the air, and, after a few circling evolutions in that element, returning to the self-same flower-heads, their chosen seats.
Both of these flies are easily captured when in this position, as they allow a near approach, and can be without hindrance swept off by a rapid side-stroke of the net.
The glorious Purple Emperor is celebrated for his predilection for a throne on the oak, though some other lofty trees, such as the ash, are occasionally honoured by the imperial presence; but his habits and locale will be referred to more particularly hereafter.
That lovely butterfly, the Silver-washed Fritillary, has a penchant for settling on the bramble, which
justifies the preference by proving itself the insect's best friend; but withal a most provoking opponent to his would-be captor, who may get him safely within the net's mouth at the first stroke, when, ten to one, the trusty bramble-hooks clutch into the gauze, and effectually prevent the quick turn of the net that should close it, while the prisoner, seeing his chance, darts out with a sharp rustle that one's irritated feelings easily interpret into a derisive laugh.
But experience will in time teach the fly-catcher the required adroitness to avoid this humiliating defeat.
