The first-instar nymph of the hibernating oviparous female In the first-instar nymph of the hibernating oviparous female, the body is slender and the ap- pendages are rather long. The body is light yellow when first hatched, but later, becomes darker and somewhat green. The an- tennae are long and are composed of three segments, the first and second of which are short while the third is comparatively very long. The groups of wax pores are conspicuous and abundant. In general, they form six longi- tudinal rows as seen from above, four rows situated medianly and one row on each lateral edge of the body. There are usually four pores in each group of the me- dian rows on the head, the thorax, and the first segments of the abdomen, but on the posterior -, ^ segments of the abdomen there Figure 2. first-instar nymph of the over- ^ f ^ u. <. ^v. c i WINTERING FEMALE, THE FORM WHICH ^^'^ more olteu Dut tttrcc porcs m PASSES THE WINTER ON THE SPRUCE a group.
