Figure 5

Stylets of a defensive nymph stuck through the epidermis of a lepidopteran larva: (a) upper focus; (b) lower focus. Capital letters on the figure indicate the apex of the rostrum of the attacking aphid (R), the socket of a seta on the epidermis of the lepidopteran larva (S), the apices of the aphid’s stylets (A), and the presumed puncture point (P). The stylets are extended from the apex of the rostrum (R) to the point A through the point P below the socket (S). Scale bars: 100 μm.
