Book excerpt: Excerpt from The Hessian Fly Mr. Herrick described the egg, and both he and Mr. Tilghman oh served and recorded the method and place of oviposition, both stating that the eggs were placed on the upper sides. Of the leaves in the long creases or furrows thereon. Prof. Riley, however, records8 the fact that this is not always the case, but that the spring brood of flies at least some times push their eggs under the sheath and between it and the straw. As to the number of Eggs placed at one time, Mr. James Worth stated that he had counted 208 eggs on a single leaf.9 Mr. Herrick says that'the number varies from one to thirty. Prof. Riley says the eggs are placed in irregular rows, Ordinarily of five or ten in each row. Prof. A. J. Cook, however, states that the female rarely deposits more than three eggs with out changing her position, and generally but one. 1 He does not definitely state that no more are deposited on each leaf, but states that In case she lays but one it takes less than a quarter of a minute and less than half a minute to lay three, when they are all laid without a change of position on the part of the fly. After laying she seems to draw in her ovipositor, soon to extend it again; at the same time crowding into it the one, two or three eggs that are next to be laid. She then flies to another leaf, alighting usually, not always, with her head toward the end of the leaf. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
