Excerpt from Notes on Some Injurious Insects The subject of injurious insects is so broad and many sided, that it is not easy to select particular points for a short review, without seeming to neglect others equally important; because every person naturally regards those insects which attack his particular plants or crops as deserving of the most attention.

Book Description
Excerpt from A Treatise on Some of the Insects Injurious to Vegetation Most insects, in the course of their lives, are subject to very great changes of form, attended by equally remarkable changes in their habits and propensities. These changes, transformations, or metamorphoses, as they are called, might cause the same insect, at different ages, to be mistaken for as manv different animals. For example, a caterpillar, after feeding upon leaves till it is fully grown, retires into some place of concealment, casts off its caterpillar-skin, and pre sents itself in an entirely different form, one wherein it has neither the power of moving about, nor of taking food; in fact, in this its second or chrysalis state, the insect seems to be a lifeless oblong oval or conical body, without a distinct head, or movable limbs; after resting awhile, an inward struggle begins, the chrysalis-skin bursts Open, and from the rent issues a butter y or a moth, whose small and abby wings soon extend and harden, and become fitted to bear away the insect in search of the honeyed juice of owers and other liquids that suffice for its nourishment.

Book Description
Excerpt from Report of Some Injurious Insects: Of the Year 1878 Without dwelling longer upon these considerations, permit me to pass directly to a brief notice of a few injurious insects which have come within my notice during the past year - a year, it may be incidentally remarked, so signalized by a scarcity of insects, that the work of collecting for the cabinet, and for scientific study, was almost abandoned. The report made at the meeting of the American Association for the Advancement of Science, at St. Louis, in August last, from entomologists representing the various portions of the United States, was unanimous, that of the Noctuidae (a family of the moths comprising the cutworms and a large proportion of the species most detrimental to the agriculturist), not one individual was to be found, where a hundred were to be met with the preceding year. Your attention will first be invited to an insect which now for the first time claims local habitation and a name in our list of insect foes. It may be called The Clover-Seed Fly - Cecidomyia trifolii n. sp. Early in the month of June, 1877, some heads of red clover (Trifolium pratense) were brought to me by Mr. T. L. Harison, Secretary of the New York State Agricultural Society, and my attention was called to some small, worm-like creatures contained within the heads, and apparently feeding upon the seeds. From their acutely elliptical form and vermiform movements when taken from the clover and placed upon a table, they seemed to be the larvae of some species of dipterous insect. All the writers upon economic entomology at my command, American and European, were searched for a notice of the insect, but no mention of it was found. During the same month, examination of heads of clover collected at West Albany, at West Troy, and it is believed at one or two other localities in the State, was made by Mr. Charles H. Peck, State Botanist, whose attention had been called to the insect, and the larvae were discovered within them. On the 19th of the same month, during a field meeting of the Troy Scientific Association held at Schroon Lake, Warren county, N. Y., the larvae, in small numbers, were found by me in some heads plucked in the village of Schroon. Subsequently my engagements were of such a nature, that I made no further observations on the "clover-seed worm" during the season. In the fore part of August, 1878, heads of red clover were handed to me by Mr. Harison, which were said to have been taken from an infested field, but I failed to detect the presence of larvae. On the 19th of the same month, six heads were sent from the President of your Society, Mr. George W. Hoffman, of Elmira, N. Y. They contained very few seeds, but the examination was not sufficiently thorough to enable me to say whether the seeds had not been formed, or if their substance had been devoured by the larvae - the latter was thought at the time to be the explanation of their paucity. Within some of the pods larvae were found very nearly filling their interior. Upon picking the flowers apart and strewing them upon a black surface, the larvae readily left their concealment and commenced traveling over the table. The flowers were shaken several times during a half-hour, until no more larvae emerged from them. A number of the pods were then opened, but all were found deserted by the occupants which they may have contained. It is probable that the larger number of the larvae had matured and left the heads before they were received by me.
