Life history and habits Nonagria oblonga Grote apparently produces only one generat ion a year. Egg-laying. --The writer has been unable to find the eggs of this species, although the work of the larvae, from the first instar on, has been observed for three seasons, two seasons around Ithaca and one season in Kansas. The young larvae may be found just as soon as the cat-tail leaves appear above the surface of the ground. In Kansas, on April 20, 1917, when the leaves of the cat-tail were not more than four inches above the surface of the ground, the larvae were found at work in the tips of the leaves. Although the larvae had evidently just started their work, and more larvae continued to appear during the following days, no eggs could 1)0 found on the plants. Again, in Ithaca, on May 20, 1918, first-instar larvae were discovered at work in the tips of the leaves, but no trace of the eggs could be discovered. This suggests the possibility that the females deposit their eggs in the fall on some of the old plants or othr objects in the field, and that the species overwinters in the egg stage The larva. --The larvae enter the leaf of the cat-tail near the tip and at once begin to work as leaf miners. In their mining they do not restrict their work to the longitudinal channels, as do the larvae of Arzamn obliqur, . but they zigzag back and forth in the leaf, cutting through both the longitudinal and the transverse partitions. They feed on the chlorophyll and on the spongy parenchyma of the plant. The larvae are strictly solitary in their habits; only occasionally do two, . . . This item ships from La Vergne,TN.<
