Another and another of these friendly meetings between them and other wasps took place in the half-hour in which I watched the sport. There were lulls in hostilities, during which an atmosphere of perfect peace and harmony seemed to reign around my bramble-bush. The flies were motionless in their ecstasy, and the hornet element seemed by common consent to keep temporarily shady, and even the butterflies seemed to forget that they had wings. But not for long, for now with a shimmering glitter our darning-needle invades the scene, and retires to a convenient perch with a ruby-eyed fly in his teeth, while a swarm of very startled butterflies tells conspicuously of the demoralization which he has left in his path. Among the butterfly representatives I at length observed one individual which at first had escaped me, an exclusive white cabbage-butterfly which sipped quietly at his leaf in the shade, and seemed to take little interest in the disreputable actions of his associates. Nothing could move him or entice him away from his convivial employment. But, alas! his folly soon found him out, for, on happening to look again, I observed he had found a new acquaintance-a hornet that had evidently been long desirous of meeting him. One by one I saw my butterfly's dismembered wings fall to the grassy jungle below, while a big black wasp proceeded to enjoy the collected sweets which he had doubtless observed were being so carefully stored away there in the shady retreat.

And now my pretty black butterfly-no, it proved to be the little day-flying grape-vine-moth, the eight-spotted black
Here is a pretty little yellow and black banded flower-fly, which is having a quiet little picnic all by himself on a bed of yarrow bloom close by. But a big black paper-hornet has suddenly seen an attraction hither also, and is soon creeping stealthily among the blossoms with a wild and hungry look. But the hornets seemed to waste their time on the flies. Seemingly confident in their less complicated wing machinery, the two-winged fly rarely sought escape until within very close range of his enemy, and his resources never seemed to disappoint him at the critical moment.
Among the insect assemblage was a large number of ants of all kinds and sizes, the common large black species being conspicuous. Here is one creeping and sipping along a grass stem. A small digger-wasp likes this grass stem too, but instead of exchanging courtesies on the subject, the wasp proceeds to bite the ant's head off without ceremony, and continues sipping at the stem as though decapitation were a mere casual incident in its daily walk.
On the same stem a big blowfly has alighted. Judging from appearances, he has had his fill of good things, and is now making his leisurely toilet in the peculiar fashion of his kind, rubbing down his back and wings with his hind legs, twisting his front feet into spirals, and ever and anon testing the strength of his elastic neck attachment as he threatens to pull his head from his body.
This worldly act has been progressing for some moments under the gaze of a big black digger-wasp, who now concludes to cut it short. When at close range with his prey, the fly suddenly discovers the unhealthy location which he occupies, and actually protruding his tongue by way of parting salute, he is off with a buzz. He has barely taken wing, however, when a still louder buzz is heard, while a great black bumblebee follows closely in his wake, until the sounds of both are lost in the distance. The hum of this bumblebee is a frequent musical feature of the entertainment, and many is the dance that is set to its minstrelsy, as the burly insect darts in among the merrymakers and is off to his perch near by. It is only as we steal away and observe him closely that we learn the secret of his occasional sorties. There on a clover blossom he sits-sipping honey? Oh no. It is honey-dew that he is enjoying, and second-hand at that, as he devours the satiated bluebottle-fly which is empaled on his black horny beak. For this is only a bumblebee in masquerade-a carnivorous fly, in truth, which, safe in its disguise of respectability, hovers in the flowery haunts of the innocents and, of course, reaps his reward.
