MMBG Newsletter No. 81 MONMOUTHSHIRE MOTH & BUTTERFLY GROUP NEWSLETTER No 81 January - March 2012. A monthly newsletter covering Gwent and Monmouthshire Vice County 35 Editor: Martin Anthoney Brindled Beauties There are three species of moth flying in the spring in Gwent that have Brindled Beauty in their name: Small Brindled Beauty, Pale Brindled Beauty and Brindled Beauty itself. The first two have flightless females so only the males fly to light, whereas both sexes of Brindled Beauty are attracted, though as with many moth species the males predominate at light. Small Brindled Beauty (Ian Rabjohns) Pale Brindled Beauty Brindled Beauty Small Brindled Beauty is the scarcest of the three species. Three were caught at Llandogo in 2011, but before that it had not been recorded in the county for 30 years. In the light of this it is encouraging that two further individuals have been seen in 2012 (at Penallt). As the name suggests, the male is smaller than the other two species, hairy, and always gives me the appearance of being too short for its wingsize. Its main foodplant is 1 oak and it is rarely found away from well-wooded areas with oaks. As the National Moth Recording Scheme map opposite shows, it is mostly a moth of south-east England, and its range only just extends into Wales. The male flies in February and March. Pale Brindled Beauty is a larger and much more widespread moth. When fresh the male has a distinct green tinge to the wings which, together with a body that is tinged pink and marked with a black pattern, serves to distinguish it from Brindled Beauty. It flies earlier in the year than Brindled Beauty, usually in February and March in Gwent, though it has been recorded as early as the November of the previous year. In parts of Britain a melanic variety forms a significant proportion of the population, but this variety is very uncommon in Gwent. The larvae feed on a range of trees and shrubs, and in early spring the flightless females can be found at dawn at the base of the trunks. Brindled Beauty flies slightly later, usually in March and April, appearing just as Pale Brindled Beauty is finishing. The earliest recorded Gwent date is 8th March. It is a more stocky, more hairy moth than Pale Brindled Beauty, and though flecked with yellow when fresh it never has the green tinge to the wings or the pink abdomen of its earlier relative. Specimens can usually also be separated by the much heavier black banding of Brindled Beauty. Like Pale Brindled Beauty, its larvae feed on a range of trees and bushes and the species is common and widespread over the whole of the county. Martin Anthoney Dotted Chestnut The headline species for early 2012 are a repetition of those for early 2011: Small Brindled Beauty and Dotted Chestnut. Small Brindled Beauty was discussed in the previous article. Apart from two historical records for Monmouthshire (1869) and Tintern (1876), nothing was heard of Dotted Chestnut in the county until the year 2000. In the twelve years of the current century there have been eight Gwent records of this nationally notable (Nb) species, all in March and April after hibernation. Similar patterns have been observed in other southern counties (eg Buckinghamshire, Glamorgan and Warwickshire) of recent records following a 100 year gap, suggesting the species is expanding its range. 2 As the map shows, the distribution of the eight recent records is along the eastern and southern edges of the county: could this be because its expansion is into the warmest parts of Gwent? The records are nearly all for gardens or open areas (eg Magor Marsh or Newport Wetlands); in Gwent, Dotted Chestnut does not appear to be a woodland species. Very little is accurately known of its early stages, as witnessed by the varied claims to be found in the literature: the caterpillar “feeds on apple”, “on most deciduous trees”, “later instars on herbaceous plants such as dandelion”, “is a cannibal” and “has an association with ants”. Clearly a lot more remains to be learned about this interesting but uncommon moth. Recent Highlights 2012 started as 2011 finished, to produce one of the warmest and driest winters and early springs on record, with only two or three days of snow in early February. This unseasonal weather has produced many very early emergences, with 3 butterflies and 12 macro moths having their earliest ever dates, with a total of 11 butterfly and 41 macro-moth species being seen by the end of March also being a new record. In such a season, do Hebrew Character and Double-striped Pug coming to light on 27th December count as extra generations for 2011, very early first generations for 2012, or perhaps both? 22nd Dec 2011 Pale Brindled Beauty and Satellite to light at Risca (Martin Anthoney) 27th Dec 2011 Hebrew Character and Double-striped Pug to light at Risca (Martin Anthoney) 29th Dec 2011 Satellite to light at Penallt (Ian Rabjohns) 2nd Jan Mottled Umber and Chestnut to light at Risca (Martin Anthoney) 7th Jan Hebrew Character at Penallt (Stephanie Tyler) 8th Jan Common Quaker to light at Risca (Martin Anthoney) 10th Jan.

  • January Review of Butterfly, Moth and Other Natural History Sightings 2019
    Review of butterfly, moth and other natural history sightings 2019 January January started dry and settled but mostly cloudy with high pressure dominant, and it remained generally dry and often mild during the first half of the month. The second half became markedly cooler with overnight frosts and the last week saw a little precipitation, some which was occasionally wintry. With the mild weather continuing from December 2018 there were a small number of migrant moths noted in January, comprising a Dark Sword-grass at Seabrook on the 5th, a Silver Y there on the 13th and 2 Plutella xylostella (Diamond-back Moths) there on the 15th, whilst a very unseasonal Dark Arches at Hythe on the 4th may have been of immigrant origin. Dark Sword-grass at Seabrook (Paul Howe) Dark Arches at Hythe (Ian Roberts) More typical species involved Epiphyas postvittana (Light Brown Apple Moth), Satellite, Mottled Umber, Winter Moth, Chestnut, Spring Usher and Early Moth. Early Moth at Seabrook (Paul Howe) Spring Usher at Seabrook (Paul Howe) The only butterfly noted was a Red Admiral at Nickolls Quarry on the 1st but the mild weather encouraged single Buff-tailed Bumblebees to appear at Seabrook on the 7th and Mill Point on the 8th, whilst a Minotaur Beetle was attracted to light at Seabrook on the 6th. A Common Seal and two Grey Seals were noted regularly off Folkestone, whilst at Hare was seen near Botolph’s Bridge on the 1st and a Mink was noted there on the 17th. February After a cold start to the month it was generally mild from the 5th onwards.

Young) Introduction The Garden Moth Scheme (GMS) welcomes participants from all parts of the United Kingdom and Ireland, and in 2017 received 360 completed recording forms, an increase of over 5% on 2016 (341). We have consistently received records from over 300 sites across the UK and Ireland since 2010, and now have almost 1 ½ million records in the GMS database. Several scientific papers using the GMS data have now been published in peer- reviewed journals, and these are listed in this report, with the relevant abstracts, to illustrate how the GMS records are used for research. The GMS is divided into 12 regions, monitoring 233 species of moth in every part of the UK and Ireland (the ‘Core Species’), along with a variable number of ‘Regional Species’. A selection of core species whose name suggests they should be found commonly, or in our gardens, is highlighted in this report. There is a round-up of the 2017-18 Winter Garden Moth Scheme, which attracted a surprisingly high number of recorders (102) despite the poor weather, a summary of the changes taking place in the GMS coordination team for 2018, and a short report on the 2018 Annual Conference, but we begin as usual with the Top 30 for GMS 2017.

  • Modelling the Population Fluctuation of Winter Moth and Mottled Umber Moth in Central and Northern Germany Anika Hittenbeck* , Ronald Bialozyt and Matthias Schmidt
    Hittenbeck et al. Forest Ecosystems (2019) 6:4 https://doi.org/10.1186/s40663-019-0162-6 RESEARCH Open Access Modelling the population fluctuation of winter moth and mottled umber moth in central and northern Germany Anika Hittenbeck* , Ronald Bialozyt and Matthias Schmidt Abstract Background: Winter moth (Operophtera brumata) and mottled umber moth (Erannis defoliaria) are forest Lepidoptera species characterized by periodic high abundance in a 7–11 year cycle. During outbreak years they cause severe defoliation in many forest stands in Europe. In order to better understand the spatio-temporal dynamics and elucidate possible influences of weather, stand and site conditions, a generalized additive mixed model was developed. The investigated data base was derived from glue band catch monitoring stands of both species in Central and North Germany. From the glue bands only female moth individuals are counted and a hazard code is calculated. The model can be employed to predict the exceedance of a warning threshold of this hazard code which indicates a potential severe defoliation of oak stands by winter moth and mottled umber in the coming spring. Results: The developed model accounts for specific temporal structured effects for three large ecoregions and random effects at stand level. During variable selection the negative model effect of pest control and the positive model effects of mean daily minimum temperature in adult stage and precipitation in early pupal stage were identified. Conclusion: The developed model can be used for short-term predictions of potential defoliation risk in Central and North Germany. These predictions are sensitive to weather conditions and the population dynamics.

  • Insect Defoliators and Their Influence on Oak Forests in the Djerdap National Park, Serbia
    Arch. Biol. Sci., Belgrade, 62 (4), 1137-1141, 2010 DOI:10.2298/ABS1004137G INSECT DEFOLIATORS AND THEIR INFLUENCE ON OAK FORESTS IN THE DJERDAP NATIONAL PARK, SERBIA MILKA M. GLAVENDEKIĆ and M. J. MEDAREVIĆ Faculty of Forestry, University of Belgrade, 11030 Belgrade, Serbia Abstract - The study of oak phytophagous insects was performed in the period 1992-2010 in the region of the Djerdap National Park. More than a third (36.67%) of the phytophages in oak forests are frequent and can occasionally cause local outbreaks. The early spring defoliator phytophages so far identified in the oak forests of the Djerdap National Park are outbreak species and are significant agents of forest ecosystem degradation and decline. The most frequent species are Tortrix viridana and Operophtera brumata. It was found that Quercus petraea was more affected by dieback then Q. cerris and Q. frainetto. Key words: Defoliators, Quercus, Tortricidae, Geometridae, Noctuidae, oak dieback UDC 502.21.5(497.11):630.19 INTRODUCTION which emerge later in spring or during summer or which have two generations.
