A. Ethogram illustrating the steps of the three different phases: long range host finding with acoustic signal and approach by flight; short range host location in which the fly orientates visually and walks towards the host; contact phase leading to larva deposition and departure from the host. The long-range approach can also lead to direct contact. If the parasitoid is disturbed it either starts again at any position of the sequence or it leaves the host.
B. Duration of the short-range phase for male and female host candidates (n = 15 in both cases; no significant difference).
C. Duration of the contact phase (n = 24 for males and n = 33 for females; p < 0.05).
D. Percentage of attacks with completed behavioral elements of the contact phase (n = 23 for males, n = 29 for females). The shading indicates percentages of attacks with positioning, timbal cut and larva deposition. The element "timbal cut" is defined as abdominal movement, not as completed cut of the timbal. The latter was only seen with males where a successful larva deposition took place.
