"The mature beetle in life rivals asparagi in beauty, but may be distinguished by its much broader elytra and its color. The ground color is orange red; each elytron is marked with six black dots, and the knees and a portion of the under surface of the thorax are also marked with black. The beetle, as it occurs on the plant when in fruit, very closely resembles at a little distance the ripening asparagus berry."—Government Printing Office, 1897

A bark beetle is one of approximately 220 genera with 6,000 species of beetles in the subfamily Scolytinae. Traditionally this was considered a distinct family Scolytidae, but nowadays it is understood that bark beetles are in fact very specialized members of the "true weevil" family (Curculionidae).

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.

(1) the Magpie Moth (Abraxas grossulariata), appearing about midsummer, has usually a black head, yellow body, and white wings spotted with black. (2) More destructive than the above is the larva of the Gooseberry Sawfly (Nematus ribesii), which plays havoc with the leaves of bushes. The larva is bluish green, with lack head, feet, tail, and spots, with twenty feet, and a length of about 3/4 of an inch when full grown.
