Midges.
Midges are small or minute flies; swarms of them are commonly seen in damp localities in the summer.
Flies.
Horseflies are unusually abundant in the neighborhood of ponds and streams.
The Robber Flies, or bee-killers, are the hawks of the insect world, preying upon their victims on the wing. In flying an insect is likely to become the victim to their sharp little dagger, which they carry in their beak. It is said that they will frequent a favorite position near a beehive and make frequent trips back and forth, and hundreds of empty bodies of bees are found beneath this perch.
The Dancefly is so called because of the up-and-down movement which they make in their swarms.
The Housefly. These insects are highly injurious to human beings because of their agency in spreading germs of such diseases as typhoid fever and Asiatic cholera. It has been discovered recently that germs of infantile paralysis are conveyed by the housefly.
THYSANOPTERA.
To this order belong very small insects known as "thrips." They are found in large numbers in flowers and in the heads of grain, chrysanthemum, hydrangea, orange-blossom, cabbage leaf, cauliflower, squash, turnips and other plants.
