Lake Maxinkuckee : a physical and biological survey / by Barton Warren Evermann and Howard Walton Clark
Lake Maxinkuckee, Physical and Biological Survey 13 to alight on the twigs and branches after roaming about in search of food. It is very active, a strong flier, and often mounts to a considerable height in pursuit of its prey. Although the abdomen of the male is seen to be highly colored with blue on close examination, both sexes appear dull brown when flying about. 3. PERITHEMIS DOMITIA (Drury) One of the smallest species, frequenting the lily-pads and pickerel-weed, flying close to the
... close to the water, and habitually keeping below the larger and stronger species as noted by Needham. The males congregate on the lily-pads some little distance from the shore and are difficult to catch because they are very wary. They can dodge a net with facility, and especially because they fly so close to the water that it is very hard to manipulate the net. The females are found closer to the shore and are not nearly so numerous as the males. Their flight here in Indiana is anything but "rather weak and a bit clumsy" as Needham records for New York State. The author spent two hours one afternoon in early September along the edge of the pickerel-weed at Twin Lakes endeavoring to catch some of these females which could be seen occasionally flying about, and finally had to come away without securing a single specimen. The females seen were always unattended by a male and deposited their eggs close to the shore amongst the Chara and Spirogyra. One specimen that had been swept into the water by the net was seized and eaten by a fish, apparently a Warmouth Bass. The adults of both sexes were obtained at Lake Maxinkuckee, Lost Lake, Bass Lake and Twin Lakes. They were especially common at Lost Lake around the Outlet where several nymphs were also obtained August 15, just ready to come forth as images. 4. CELITHEMIS EPONINA (Drury) One of the skimmers and the largest of the genus in the State, both sexes rust-colored throughout, with large brown spots on the wings, the male more brightly colored than the female. This species and Libellula luctuosa were the two most common dragon-flies at all the lakes visited. They appeared before our arrival and were still roaming about at the middle of September. The female of this species is nearly always held by the male when depositing her eggs, and the two are seen flying about together more frequently than any other species. Since the eggs are deposited in the clean water, often a long distance from any vegeta-Lake Maxinkuckee, Physical and Biological Survey 31 Among the more common, homely bugs, the most abundant species was Oncopeltus fasciatus Dall, on the milkweed blossoms. Cicadas, or harvest flies, were conspicuous by their absence. Throughout Indiana, as in other parts of the country, one of the characteristic sounds of summer is that of the Dog-day Locust or Harvest Fly. We have no record of hearing it at the lake. It is possible that it does not like the sandy soil. An odd-shaped tree hopper, Enchenopa binotata, was noted in abundance laying white eggs in masses on twigs of the hop tree, Ptelea trifoliata, August 10, 1906, and examples were collected. Plant lice were abundant on the pondweed leaves (Potamogeton natans) in Lost Lake, making a messy looking mass. They were also present, but in fewer numbers, on the water-lily leaves. ORDER TRICHOPTERA THE CADDIS-FLIES The Caddis-flies are among the most interesting of our insects. Although about 150 species have been described from America, there are doubtless many remaining undescribed. The adults are not well known to the general public, in spite of the fact that at times they appear in myriads. The larvae, which are aquatic, are much better known. Every one who has spent any time along mountain streams, or even about other streams, or lakes, if at all observing, can not fail to have noticed the cleverly built, often beautiful, cases which these larvae build of sand, brightly colored pebbles or bits of wood, held together by silken threads. As Professor Kellogg has well said: There is a great variety in the materials used, and in the size and shape of the cases, each kind of Caddis-worm having a particular and constant style of housebuilding.
