Figure 16
Eclosion and immatures of Scenergates viridis. (a) Three stages of hatching: arrow points to the pronymphal exuvia. (b) The anterior end of a pronymph in ventral view, with the first-instar nymph’s head emerging from the V-shaped rupture at the apex. (c) The inner surface of a dry overwintered gall after the nymphs have hatched out, with numerous pronymphal exuviae attached to eclosion slits; one exuvia is magnified (inset). (d) Two differently colored first-instar nymphs from the same brood. (e) Female (below) and male (inset) last-instar nymphs; the nymphal gall was opened artificially. (f) A gall which failed to open, here opened artificially to expose the dead female atop the mass of dead hatchlings. Scale bars: 0.5 mm ((a), (d)), 50 μm (b), 1 mm (c), 1 mm (f).
