- Syrian Ants
The Ant is mentioned twice in the Old Testament, both times in the Book of Proverbs (vi. 6 and xxx. 25). Ants are characterized as being exceeding wise, and in both passages are commended for their diligence in preparing their food in the summer, thus by their fore-sight providing for their winter sustenance. Such is at least the` obvious implication contained in the text. This habit was, and is still, contradicted by some writers, from their knowledge of the ways of European ants, which are dormant in the winter, and therefore stand in no need of food. - Tarantula

The body is seen to be divided into two parts, connected only by the narrow joint, A, just behind the last pair of legs. The front half of the body, called the thorax, contains the stomach, the central part of the nervous system, and the large muscles which work the legs and jaws. The hinder half, the abdomen, contains the intestine, the breathing-organs, the principal circulating-vessels, the organs of reproduction, and the spinning-organs. Connected with the thorax are six pairs of limbs, four pairs of legs, B B B B, a pair of palpi, C, and a pair of mandibles, D. - The house or typhoid fly (Musca domestica)
The house-fly breeds by preference in horse manure. Indeed, It has been found that they would develop in almost any fermenting organic substance. Thus, they have been bred from pig, chicken, and cow manure, dirty waste paper, decaying vegetation, decaying meat, slaughter-house refuse, sawdust-sweepings, and many other sources. A fact which makes them especially dangerous as disease-carriers is that they breed readily in human excrement. - The Italian tarantula
- The Locust
Sometimes millions of locusts come upon the wind, and devour every green thing, so that nothing is left for man or beast. - The Pursuit

- Trypanosoma brucei
By trypanosomiasis is meant a condition of animal parasitism, common to man and the lower animals, in which trypanosomes, peculiar flagellate protozoa, infest the blood. Depending upon the species, they may be harmless, producing no appreciable ill-effect, or pathogenic, giving rise to conditions of disease. A number of these are known to be transferred by insects. The trypanosomes are elongated, usually pointed, flagellated protozoa in which the single flagellum, bent under the body, forms the outer limit of a delicate undulating membrane. It arises near one end of the organism from a minute centrosome-like body which is known as the blepheroplast, and at the opposite end extends for a greater or less distance as a free flagellum. Enclosing, or close beside the blepheroplast is the small kinetonucleus. The principal nucleus, round or oval in form, is situated near the center of the body. Asexual reproductions occurs in this stage, by longitudinal fission, the nucleus and the blepheroplast dividing independently of one another. From the blepheroplast of one of the daughter cells a new flagellum is formed. - Two birds watching a bug

- Upper Side of Epeira Vulgaris
The head is not separated from the rest of the body, as in insects, but forms, with the thorax, one piece. On the front of the head are eight eyes, Q, which are differently arranged in different spiders. On the abdomen are several pairs of dark smooth spots, which mark the ends of muscles extending downward through the abdomen. The markings of this spider are very complicated. The spot on the middle of the front of the abdomen is a very common one, and, in some spiders, extends the whole length of the body. The waved lines on each side are also common, and, in long-bodied spiders, often form two bright-colored stripes, or rows of spots, running nearly straight the whole length of the abdomen. - Violacea Butterfly
Larva, Protected by Ants, Feeding on Flower-buds of Dogwood. Why this species, and doubtless many others of its family, are thus favored, will soon be apparent. Ants may be seen wherever these larvæ may be found, ever ready to receive the honeyed secretion when it pleases the little creatures to eject it, but all the while exercising the closest vigilance lest some wary ichneumon may come along and deal a thrust of its ovipositor, which means misery and ultimate death to their helpless friends. So intent is the larva, with its head buried in the flower, upon its feeding, and so quietly and stealthily does the ichneumon approach its intended victim, that hardly a single individual would be left to tell the story of its existence were it not for the ants. The larvæ know their protectors, it would seem from their actions, and are able and willing to reward their services. The advantage is mutual, and the association friendly. No compelling by rough means on the one part is noticeable, and no reluctant yielding on the other. All demonstrations made by the ants are of the most gentle character. They caress, entreat, and as they drink in the sweet fluid, lifting their heads to prolong the swallowing, they manifest to the utmost their satisfaction and delight. It is amusing to see them lick away the last trace, caressing the back of the segment with their antennæ as they do so, as though they were coaxing for a little more. - Wandering Crab Spider

The Wreathed Weaving Spider ( Theridium redimitum), which occurs quite commonly, especially in gardens, becomes at most 5 mM. long; this fat little spider inhabits all kinds of low-growing herbs and shrubs; here it spins (fig. 1) a few leaves together by irregularly oriented threads, on which the small animals that make up its food stick to. The mother attaches the spherical, bluish egg sac to a leaf (fig. 2), keeps watch next to it until the young have hatched, and continues to do so for the few days of their cohabitation. These beautiful spiders are very variable in color and drawing. Transparent and almost white in their early youth, spotted black only on the back of the abdomen; towards the end of June, in July and in August, they have taken on a pale yellow color, some plain, others with a stain on the abdomen, which can be pure pinkish red or partially greenish, circular or oval. In addition, the rim and a line across the center of the head-breast, 6 pairs of round dots on the abdomen, the tip of the probes and the shins are black. grab.
