Vayssiere, of the Faculte des Sciences, at Marseilles. A propos of the larvae of Ephemera or May-flies, we must speak of one of the entomological rarities of France, the nature and zoological place of which it has taken more than a century to demonstrate.

Down in the still, pure depths of these hidden lakelets you may also find the larvae of innumerable insects and a great variety of beetles, while the air above them is thick with humming wings, through the midst of which fly-catchers are constantly darting.

But woe to the black bumblebees discovered in their mossy nests in the ground! With a few strokes of their huge paws the bears uncover the entire establishment, and, before time is given for a general buzz, bees old and young, larvae, honey, stings, nest, and all are taken in one ravishing mouthful.

These vegetables were nearly destroyed by the larvae of the cabbage fly, which would have afforded the birds many fine, rich meals. This comparatively feeble insect has been allowed by the throngs of birds to spread over the whole continent.

The Indians of the western slope venture cautiously over the passes in settled weather to attend dances, and obtain loads of pine-nuts and the larvae of a small fly that breeds in Mono and Owen's lakes, which, when dried, forms an important article of food; while the Pah Utes cross over from the east to hunt the deer and obtain supplies of acorns; and it is truly astonishing to see what immense loads the haggard old squaws make out to carry bare-footed through these rough passes, oftentimes for a distance of sixty or seventy miles.

They are the larvae of Phryganeas this of a true moth. The male of this moth will come out, as a moth should, and fly about on four handsome wings. The female will never develop her wings, but remain to her life's end a crawling grub, like the female of our own Vapourer moth, and that of our English Glow-worm.

The "pots" were baited with most unpleasant dainties, but nasty as these were they were not so unsavoury as the food which the crayfish found for themselves and thoroughly enjoyed, such as dead water-rats and dead fish, worms, snails, and larvae.

He buries it entire, on the spot, in a cellar where the thing, duly ripened, will form the diet of his larvae. He buries it in order to establish his progeny therein. This hoarder of dead bodies, with his stiff and almost heavy movements, is astonishingly quick at storing away wreckage.

Now, to begin with, we see natural sections which adopt as their prey different species of one and the same order, in one and the same group. Thus the Ammophilae hunt exclusively the larvae of the night-flying Moths. This taste is shared by the Eumenes, a very different genus. "The Mason-wasps" by J. Henri Fabre, translated by Alexander Teixeira de Mattos: chapter 1. Cf.

They advance in a long column live or six deep, while thinner columns forage on either flank, till they arrive at a mass of rotten wood abounding in insect larvae, when they surround it, and do not again move forward till every particle of food has been carried off! When they discover a wasp's nest, they attack the papery covering to get at the larvae pupae and newly-hatched wasps.
