Someautumn and winterobservationsofHalyziasedecimguttata (L.) (Col.: Coccinellidae) with noteson aconcentration ofwinteringladybirds On 24 October 1999 a concentration of ladybirds was discovered gathered upon fence posts along the margin of a small secondary wood near Whittlesford, Cambridgeshire. Present among them were at least 25 examples of the Orange Ladybird Halyzia sedecimguttata. The posts were beneath overhanging Sycamore Acerpseudoplatanus, a tree favoured by this species. Other familiar ladybirds were alsopresent, notably largenumbers ofSixteen-spotMicraspissedecimpunctata (L.). A return visit was made to the site on 6 February 2000, in an effort to arrive at a clear estimate ofthe number ofwintering ladybirds present. The insects were found to be utilising some 400 metres of (mostly) wooden posts of varying diameter, and almost withoutexception were facing between north-east and south (the sides facing the wood). This observation parallels previous records reported by Adrian Fowles (Majerus, 1994. Ladybirds. New Naturalist's Series, HarperCollins, pp. 93-94). Fowles' interpretation, endorsed by Majerus, is that the ladybirds are taking up positions sheltered fromprevailing south-westwinds. There were indications that wood which had been treated with timber preservative, as some ofthe largerposts had been, were unpopular. On this occasion only eight H. sedecimguttata were located. Most of these were on the posts themselves, either in exposed positions (but usually in company with other coccinellids), orin shelteredcrevices, with one on the underside ofafence wire; one individual was active. By far the most numerous species present was M. sedecimpunctata: extrapolating from a series ofcounts and estimates suggested that a total in excess of50,000 were utilising the fence posts and the grass and other vegetation at their bases; it is likely that more were using this latter habitat than could be observed. Large aggregations ofM. sedecimpunctata is not unusual - this species habitually forming large over- wintering aggregations (Majerus op. cit.). Also present were 20 Seven-spots Coccinellaseptempunctata (L.) in avariety oflocations andpositions,justone Two- spotAdalia bipunctata (L.), and a single Kidney-spot Chilocorus renipustulatus (L.) activeonafence inthewooditself. On 16January 2000, a singleH. sedecimguttata was discovered wintering inside a telephone box, ofthe modem open design, at Bricket Wood, Hertfordshire, a semi- natural woodland locality where the species has previously been recorded. The individual had adopted an inverted position against the roof of the box, similar to that employed by this and other ladybirds when utilising natural wintering sites on the underside of tree branches. It may be speculated that the insect had originally been attracted by the light, as moths often are to this and other public telephones. 102 ENTOMOLOGIST'SRECORD,VOL. 112 25.V.2000 This suggestion is supportedby previous records ofladybirds attracted tomoth traps (Majerus, 1990. Ladybirds at light. Bull. Amat. Ent. Soc, 49: 197-199). Majerus notes that Halyzia sedecimguttata is more strongly attracted to light than other Britishladybirds. I amgratefulto DrMike Majerus forhis helpfulcomments, viathe Editor, on the initial draft of this note.- C. M. Everett, Wolfson College, CambridgeCB3 9BB. The ladybirdasatwinklein theeyeofan angel The Orange Ladybird Halyzia sedecimguttata (L.) was once regarded as rather uncommon and, although it isnow known tobequite widespread, itisnevertheless a handsome insect and not one to be come across every day. It is a striking yellowish orange, with pale creamy white spots and has a strange transparent rim at the sides andfrontofthe thorax, extending outoverthehead. Fowler (1889. The Coleoptera ofthe British Islands 3: 166) and Joy (1932. A practical handbook ofBritish beetles, p. 522) both describe the Orange Ladybird as "local", unusual for a ladybird since most species are very common and widespread. A tentative list ofscarcity statuses put about by Hyman (1985. Aprovisional review ofthe status ofBritish Coleoptera. Invertebrate Site Register Report 60: NCC), suggested that it might even be considered as nationally scarce (Notable B, i.e., recordedfrombetween 31 and 100ofthe ten-kilometre squares oftheNationalGrid). However, during the 1980s, Halyzia seems to have been recorded more often. Provisional Notable status was not confirmed when the final review of scarce and threatenedbeetles wasproducedby HymanandParsons (1992.A reviewofthescarce andthreatenedColeopteraofGreatBritain. UKNatureConservation3: JNCC). There is no doubt that some ofthis increased recording was due to the fact that a specific association with sycamore Acerpseudoplatanus trees was first noticed at this time. The Orange Ladybird is a mildew (mould) feeder, rather than an aphid predator, and sycamores seem to be particularly prone to mildew on their leaves. Once thisfactwasknowntheladybirdwasmuchmoreoftenrecorded. The Orange Ladybird's over-wintering habits are usually described as in leaf litter, on tree trunks or in ivy clumps, especially near sycamores (Majerus, 1994. Ladybirds. New naturalist 81: Harper Collins), and although small aggregations of over-wintering Orange Ladybirds are recordedthey are notfrequent. I was intrigued, therefore, to find several specimens huddled together on various gravestones and, in particular, on a stone angel, a delicately carved and gently lichen-encrusted Victorianheadstone, inNunheadCemetery, southLondon,on 1 January 2000. Six of them, together with a specimen of the Pine Ladybird Exochomus quadripustulatus (L.) were snuggled together in the angel's hairline, others were restingunderherearandonherneck, andonewastuckedintohereye socket. Ladybirds are steepedinmythandmetaphor. From signs ofgoodlucktoomensof imminent matrimony, from the gardener's friend to the child's delight, these pretty beetles are welcomed and celebratedby all. Buthas anyone everthoughtto describe aladybird as atwinkle in the eye ofan angel?-RichardA. Jones, 135 FriemRoad, EastDulwich,London SE22OAZ.
