from the same host. Although evidently not obligatorily so (see below), it is probably largely univoltine, and the winter is passed inside the diapausing host larva. The host is arboreal, and when parasitised shows strong climbing behaviour just before being mummified, such that mummies are formed in exposed positions. It was readily reared from
in culture, but quantitative data are not available owing to high overwintering mortality. The notes that follow relate to a single, virgin, female. This female showed great interest in an egg mass of its host, antennating the dense covering of setae left by the female moth, and probing also with the ovipositor but probably without attempting to oviposit except into fully eclosed larvae as they exited from the felted covering. Neither legs nor antennae were used to manipulate such hosts, and the process was achieved with a single insertion of the ovipositor. In subsequent trials, second instar hosts were offered naked, and it was clear that there was an injection of a temporarily paralysing venom (detected by a clear jerk of the wings) before actual oviposition took place, although the ovipositor was usually not removed in the interim. As with the emerging first instars, the use of antennae or legs to hold the host was minimal so usually the ovipositor was all that was in contact with the host, pinning it against the substrate, and oviposition usually took about (often just over) 2 minutes, without a period of post-oviposition assessment or at most with only a minimal one. The long setae of third instar hosts were a good deal harder for the female to penetrate, but some ovipositions into this instar also occurred.
proved to be, like its host, partly plurivoltine. The host invariably overwinters as a partly grown larva in a densely spun hibernaculum, and the adult moths appear in the following vi/vii. In captivity, a small proportion of host larvae (available from about vii onwards) from the resulting eggs fed up rapidly and produced a second generation of the moth, while the majority developed only slowly and entered hibernation in the autumn (often not until the end of ix) while still relatively small, joined at that time by offspring of the second generation. The parasitoid invariably overwinters as a small larva within these diapausing hosts. From overwintering hosts mummification takes place in about (
)vii, to oviposit into the young hosts that appear soon after. In host individuals with the accelerated growth pattern the host was mummified in about viii and the adult parasitoids emerged in ix (N = 4). At this time host larvae, from both generations, are still available prior to constructing their hibernacula. The cohort of hosts with accelerated growth that produced a second generation during the culture experiments arose in control groups as well as among the parasitised hosts, so this behaviour was not the result of having been parasitised: rather, it seems likely that only the growth of host individuals independently destined for a second generation would have provoked similar early development by the parasitoid. Hosts bearing the parasitoid entered winter diapause on average an estimated 8-10 days sooner than unparasitised ones. For the hibernaculum, the parasitised hosts constructed a weak outer
, moulted, and then made a much denser inner chamber isolated from the exuvium, while unparasitised controls usually moulted before commencing construction of a single chamber. Parasitised hosts (N = 10) broke diapause in spring over a period of 22 days, on average 8.0 days later than controls (N = 9) which emerged from their hibernacula over a period of 11 days (see also
x), suggest that a single generation of rather long-lived individuals is the norm. It appears to have colonised Britain only recently; the first specimens known to us were collected in 1999 in Berkshire, since when it has been taken in MV traps in the SE corner of England fairly regularly. It is unlikely to have been long-overlooked in Britain, as its rather common and attractive host larva is conspicuous, readily identified, often reared and, when mummified by this parasitoid, often easily seen in a sun-exposed position.

The extent of dark colouration is highly variable, and is often poorly developed in the British population. In males especially, the colour (including scape and even stemmaticum) can be rather uniform orange to light honey-brown. Because it can lack the colour characters usually plain in females, the male of this species can superficially resemble some of the relatively large orange species with big ocelli and antennal segments in the range 41-48 that fall into the residual

female types (including the holotype) should have 35-38 antennal segments and the male types 42-43 segments; most likely the antennal counts for the female types given by Tobias result from a lapsus or typographical error and should be 45-48.
