(Scopoli) which hibernates as a pupa and would not provide a means for the parasitoid to overwinter. The essentially univoltine host overwinters as a small caterpillar, within which the parasitoid overwinters as an early (probably first) instar larva. The mummies of penultimate instar hosts are made in exposed situations on very narrow stems etc. in about early June and, no doubt aided by their almost black and hence heat-absorbing colour, adult emergence follows quickly; the mummies otherwise being subject to high levels of pseudohyperparasitism. The adult females are unwilling to mate soon after their emergence in the morning but become highly receptive in early evening, offering themselves to males at the first contact which sometimes happens before the males are fully aware of them, and repeated copulation bouts with the same or another male frequently ensue over the next tens of minutes. The new generation of hosts is not available for several weeks, but the adult females are long-lived (confirmed in captivity), and have been collected from June well into the autumn (as late as October). The host has been in severe decline in Britain in recent years, apart from its strong presence on

in parts of Scotland, which remain also a stronghold for the otherwise declining parasitoid. When surveying for the presence of the parasitoid, undersized hosts collected in mid to late May are the most likely to yield results.
