(a) Newborn nymphs of M. punctatissima resting in aggregation near the eggshells. Scale bar, 1 mm. (b) Resting nymphs (arrow) and wandering nymphs (arrowheads) from an experimental egg mass that consists of 15 eggs and a capsule. Scale bar, 1 cm. (c) Relationship between the number of nymphs per capsule and the number of wandering nymphs among the experimental egg masses. The mean and standard deviation are shown. Numbers of egg masses examined are indicated in the plots. Kendall's rank correlation test, p<0.0001.
