FIGURE 18. Egg laying in H. lineata. Yolky eggs are contained in contiguous egg sacs which are attached to venter of the parent. A (HL-8D), advanced ova in ovisacs, soon to be laid. B (HL-8G), recently deposited egg sacs on venter. C (HL-8J), close-up of early embryos emerging from egg sacs. Note characteristic body width of this brooding individual. D, several contiguous egg sacs dislodged from a brooding parent. Scale bars (approximate): (A,B) 1.0 mm, (C,D) 0.5 mm.
