"They carry the air required for their respiration in a space left for this purpose between the wings and the back. They are very active and predaceous animals, and when captures, some of them often inflict a painful wound with their powerful rostru,. Several species may be met with in almost any piece of water." — Goodrich, 1859

The hessian fly or barley midge, Mayetiola destructor, is a species of fly that is a significant pest of cereal crops including wheat, barley and rye. Though a native of Asia it was transported into Europe and later into North America, supposedly in the straw bedding of Hessian troops during the American Revolution (1775–83). There are usually two generations a year but may be up to five. In the spring the dark-coloured female lays about 250 to 300 reddish eggs on plants, usually where the stems are covered by leaves; the larvae feed on the sap and weaken the plants so that they cannot bear grain.

The horse-flies or <em>tabanidae</em>, comprise another set of troublesome creatures, of medium or large size. They have short, broad heads, enormous eyes, and short, though many jointed, feelers. The abdomen is oval, a little flattened, and the body convex and powerful. The mouth parts are well developed, consisting of a series of five sharped-pointed lancets so rigid that they readily pierce the skin and draw blood almost as soon as they touch.

The Goshawk (Astur palumbarius) is a hawk abundant in the forest regions of northern Europe and Canada, but rarely seen southward, except occasionally in winter. The upper part of the body is ash-brown, with four broad dark bands on the tail; the under part white, barred with black. The bird is bold and rapacious, and remarkable for the skillful turns by means of which it follows every movement of the quarry. It was one of the favorite hawks in falconry.

The Great Crested Grebe (Lophæthyia cristata) is a fresh-water, migratory, diving bird of the family Podicipidæ. It has a duck-like body, brownish and white plumage, long neck, short wings, no tail, and large, flattened toes furnished with lobate membranes serving the purpose of webs. Most of its life is spent in fresh water lakes and ponds, but in winter and during migration, it often resorts to the sea. It is an excellent diver. The nest is made of rushes and other aquatic plants and usually floats on the water, being loosely anchored to weeds and grass. It is found in nearly all parts of Europe and Asia.
