What reading level is Alternating Generations; a Biological Study of Oak Galls And Gall Flies book?
To quickly assess the difficulty of the text, read a short excerpt:
For instance, if a fly is reared from a leaf-gall, and is furnished with an ovipositor which is not adapted for piercing leaves, it may be inferred with certainty that another generation, capable of pro- ducing leaf-galls, belongs to this fly.
It will be found of interest, therefore, to review the various forms of ovipositor described.
I. Neuroterus-Spathegaster Group.
A glance at the illustrations ^ of the two ovipositors will enable us to appreciate their great difference. In Neuroterus laevi...usculus (Fig. 2) the ovipositor is very long and spirally coiled ; in Spathegaster albipes, on the contrary (Fig. 2'^), it is short and slightly curved.
The other species of Neuroterus show a somewhat shorter ovipositor, especially Neuroterus fumipennis (Fig. 3). Spathegaster ovipositors do not vary. The Neuroterus ovipositor has a hook-shaped point, and can therefore never penetrate perpendicularly into a bud. The Spathegaster ovipositor, being only slightly curved, can pierce vertically the surface of the leaf.
