Figure 5. Development of parthenogenetic Paratanytarsus laccophilus species-group progeny in the 15.3 °C treatment in 2016. a) An egg mass freshly laid on 11 July. b) The same egg mass on 15 July, just before hatch. c-g) Daily progression of development. c) Eggs on 12 July 2016 at one day old. d) At two days old. e) At three days old, eye spots (arrow) and head capsules were evident inside the egg. f) At four days old, eye spots and head capsules (arrow) were well-defined within the egg. g) Larvulae (arrow) hatched on 16 July, five days after oviposition. Several vacated eggs are clearly notable. Scale bar = 1 mm for a and b, and 250 μm for c-g.
