What reading level is The Hessian Fly in the United States book?
To quickly assess the difficulty of the text, read a short excerpt:
Polygnotua zosini Walk.
Trichtiais remulus Walk.
Before taking up in detail the species of parasites known to infest tbe insect in America, we may stop to notice the remarkable studies of Marcbal upon the early development of some of the parasites as observed by him. The most striking of these relate to the early stages of Tricha- 8is remulus, which is said to deposit its eggs in May and June, either in the egg or the very young larva of the Gecidomyia, the larva? of the Platygaster being alway...s encountered in the very young larva of the Cecidomyia. In some cases where the punctures by the parasite have been too numerous the larvae attacked die and dry up without com- pleting their development. In such cases the parasites are arrested in their development and perish. More often the Oecidomyian larva con- tinues to feed and grow to the time of forming the puparium. The puparia of the attacked larvae are smaller and paler than those of nor- mal larvae, sometimes even of minute size, generally very flat, and always of irregular form.
