63An Overview of Phylloxera in Vines
It is yellow-brown in color and horrible to look at through a magnifying glass, but it cannot be seen very clearly otherwise, as it is only a half to one millimeter long. Its life cycle is extremely complicated and varies according to the conditions under which it lives, but it breeds and multiplies at a prodigious rate. The female lays a single egg in the stem of the vine during the autumn; this hatches out in the spring to give a fundatrix, which may lie anything up to thirty eggs.
