The Colorado Potato Beetle Observations And Studies
Watch for the first appearance of the adult beetles in the spring when the potatoes are just beginning to come up. They pass the winter under ground and in the spring come out ready to lay eggs on the young potatoes. Collect and examine the adults. How many stripes have they? Collect packets of eggs and count them. How many eggs in most packets? How are they attached to the leaf? How large are the grubs when they hatch from the egg? Examine the grubs where they are feeding on pot
Write a short description of the eggs, grubs and beetle, its work and means of killing it when it is feeding on potatoes. Make careful drawings of a cluster of eggs, the grub and the beetle.

<p>Collect all the different kinds of mosquitoes you can find and note difference in size and markings. Do you find the malarial fever mosquito in your region? Is malarial fever common during the summer and fall? Are there any old stagnant ponds or... A BEE-HUNTER - THE PHILANTHUS AVIPORUS
To encounter among the Hymenoptera, those ardent lovers of flowers, a species which goes a-hunting on its own account is, to say the least of it, astonishing. That the larder of the larvae should be provisioned with captured prey is natural enough... A DANGEROUS DIET
The Scolia's egg is in no way exceptional in shape. It is white, cylindrical, straight and about four millimetres long by one millimetre thick. (About .156 x .039 inch.--Translator's Note.) It is fixed, by its fore-end, upon the median line of the v... A DIG AT THE EVOLUTIONISTS
To rear a caterpillar-eater on a skewerful of Spiders is a very innocent thing, unlikely to compromise the security of the State; it is also a very childish thing, as I hasten to confess, and worthy of the schoolboy who, in the mysteries of his desk... A Honey Bee Never Volunteers An Attack Or Acts On The Offensive When It Is Gorged Or Filled With Honey
The man who first attempted to lodge a swarm of bees in an artificial hive, was doubtless agreeably surprised at the ease with which he was able to accomplish it. For when the bees are intending to swarm, they fill their honey-bags to their utmost c... A MEMORABLE LESSON
I take leave of the mushrooms with regret: there would be so many other questions to solve concerning them! Why do the maggots eat the Satanic bolete and scorn the imperial mushroom? How is it that they find delicious what we find poisonous and why... A PARASITE OF THE MAGGOT
The dangers of the exhumation are not the only ones; the Bluebottle must be acquainted with others. Life, when all is said, is a knacker's yard wherein the devourer of today becomes the devoured of tomorrow; and the robber of the dead cannot fail t... A TRUFFLE-HUNTER THE BOLBOCERAS GALLICUS
In the matter of physics we hear of nothing to-day but the Roentgen rays, which penetrate opaque bodies and photograph the invisible. A splendid discovery; but nothing very remarkable as compared with the surprises reserved for us by the future, w... Age Of Bees
The queen bee, (as has been already stated,) will live four, and sometimes, though very rarely, five years. As the life of the drones is usually cut short by violence, it is not easy to ascertain its precise limit. Bevan, in some interesting stateme... AN INVADER - THE HARICOT - WEEVIL
If there is one vegetable on earth that more than any other is a gift of the gods, it is the haricot bean. It has all the virtues: it forms a soft paste upon the tongue; it is extremely palatable, abundant, inexpensive, and highly nutritious. It i... ANOTHER PROBER (PERFORATOR)
What can he be called, this creature whose style and title I dare not inscribe at the head of the chapter? His name is Monodontomerus cupreus, SM. Just try it, for fun: Mo-no-don-to- me-rus. What a gorgeous mouthful! What an idea it gives one of ... Artificial Rearing Of Queens
The distress of the bees when they lose their queen, has already been described. If they have the means of supplying her loss, they soon calm down, and commence forthwith, the necessary steps for rearing another. The process of rearing queens artifi... Artificial Swarming
The numerous efforts which have been made for the last fifty years or more, to dispense with natural swarming, plainly indicate the anxiety of Apiarians to find some better mode of increasing their colonies. Although I am able to propagate bees ... Bee-dress
Timid Apiarians, and all who are liable to suffer severely from the sting of a bee, should by all means furnish themselves with the protection of a bee-dress. The great objection to gauze-wire veils or other materials of which such a dress has been ... Bees Cannot Under Any Circumstances Resist The Temptation To Fill Themselves With Liquid Sweets
It would be quite as easy for an inveterate miser to look with indifference upon a golden shower of double eagles, falling at his feet and soliciting his appropriation. If then we can contrive a way to call their attention to a treat of running swee... BRAMBLE-DWELLERS
The peasant, as he trims his hedge, whose riotous tangle threatens to encroach upon the road, cuts the trailing stems of the bramble a foot or two from the ground and leaves the root-stock, which soon dries up. These bramble-stumps, sheltered and pr... Breeding Cage Observations

Brillat-Savarin, when pronouncing his famous maxim, "Tell me what you eat and I will tell you what you are," certainly never suspected the signal confirmation which the entomological world would bestow upon his saying. Our gastrosopher was speaking ... Comb
Wax is a natural secretion of the bees; it may be called _their oil or fat_. If they are gorged with honey, or any liquid sweet, and remain quietly clustered together, it is formed in small wax pouches on their abdomen, and comes out in the shape ... Directions For Collecting
