We demonstrate that the omnidirectional green colour arises from the gyroid cuticular structure grown in the domains of different orientation. We also show that this three-dimensional structure, operating as a biophotonic crystal, gives rise to various polarization effects. We briefly discuss the possible biological utility of the green coloration and polarization effects. Keywords: structural colour; butterflies; Lycaenidae; gyroid; photonic bandgap materials 1.

London Loop. Section 3 of 24
Transport for London. London Loop. Section 3 of 24. Jubilee Country Park to Gates Green Road, Wickham Common. Section start: Jubilee Country Park. Nearest station Petts Wood to start: Section finish: Gates Green Road, Wickham Common. Nearest station Hayes (Kent) to finish: Section distance: 9 miles (14.5 kilometres). Introduction. This section of the LOOP passes through attractive countryside with strong links to Charles Darwin who described the countryside around the village of Downe as 'the extreme verge of the world'. The walking is generally easy, but with a few longish, steep slopes, stiles and kissing gates and some small flights of steps. Much of it is through commons, parks and along tracks. There are cafes and pubs at many places along the way and you can picnic at High Elms, where there are also public toilets. The walk starts at Jubilee Country Park and finishes at Hayes station. There are several bus routes along this walk. Continues Continues on next page Directions. To get to the start of this walk from Petts Wood station exit on the West Approach side of the station and turn right at the T-junction with Queensway. Follow the street until it curves round to the left, and carry straight on down Crest View Drive. Take Tent Peg Lane on the right and keep to the footpath through the trees to the left of the car park. After 100 metres enter Jubilee Country Park, and join the LOOP. From the car park on Tent Peg Lane enter the park and at the junction of several paths and go through the gate on the left and follow the metalled path for about 150 metres, then branch left. -

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. -

The Infrastructure Delivery Plan (IDP) provides: • background and context to key infrastructure that has been delivered recently or is in the process of being delivered, • an analysis of existing infrastructure provision, • stresses in the current provision, • what is needed to meet the existing and future needs and demands for the borough to support new development and a growing population, as envisaged through the Council’s emerging Local Plan 2030. 1.2 The IDP has been informed through discussion and consultation with relevant service providers operating in the Borough, alongside reviewing existing evidence and publications (such as management plans). 1.3 The IDP is supported by various appendices, as follows: • Appendix 1: Links to evidence and management plans – several stakeholders steered us towards their respective management plans and publications as a way of responding to our consultation and questions. -
Notes on the Probable Course of the Roman Road from Lympne to Dover
Archaeologia Cantiana Vol. 62 1949 NOTES ON THE PROBABLE COURSE OF THE ROMAN ROAD FROM LYMPNE TO DOVER By IVAN D. MARGARY, F.S.A. THE existence of a Roman road connecting Lympne with. Dover is attested by its actual appearance upon the diagrammatic map known as the Peutinger Table. No traces of the road had, however, been identified, and the growth of Folkestone and its outskirts has now put much of the probable route beyond direct investigation. Some notes were put forward by the late S. E. Winbolt in his book Roman Folkestone (Methuen, 1925) as a tentative approach to the subject, and it was with a view to testing these on the ground that the present investigation was made. There is general agreement that the existing road along the old cliffs at Lympne represents the Roman road. East of Shipway Cross it bends a good deal and is probably an old ridgeway track rather than an engineered road, but there seems no reason to disregard it as a part of the route on that account. We thus arrive at the crossing of the Brockhill Stream, just at the western entry to Hythe, and it seems clear that the trackway is directly continued by an old lane, now in part only a footpath, straight up the hill north-eastwards to Saltwood, making no doubt for the hills inland. Consideration of the eastward course of a Roman road from this point is very largely determined by the topography, which here shows marked features some of which would entirely preclude the making of a direct road. -
Effect of Different Mowing Regimes on Butterflies and Diurnal Moths on Road Verges A
Animal Biodiversity and Conservation 29.2 (2006) 133 Effect of different mowing regimes on butterflies and diurnal moths on road verges A. Valtonen, K. Saarinen & J. Jantunen Valtonen, A., Saarinen, K. & Jantunen, J., 2006. Effect of different mowing regimes on butterflies and diurnal moths on road verges. Animal Biodiversity and Conservation, 29.2: 133–148. Abstract Effect of different mowing regimes on butterflies and diurnal moths on road verges.— In northern and central Europe road verges offer alternative habitats for declining plant and invertebrate species of semi– natural grasslands. The quality of road verges as habitats depends on several factors, of which the mowing regime is one of the easiest to modify. In this study we compared the Lepidoptera communities on road verges that underwent three different mowing regimes regarding the timing and intensity of mowing; mowing in mid–summer, mowing in late summer, and partial mowing (a narrow strip next to the road). A total of 12,174 individuals and 107 species of Lepidoptera were recorded. The mid–summer mown verges had lower species richness and abundance of butterflies and lower species richness and diversity of diurnal moths compared to the late summer and partially mown verges. By delaying the annual mowing until late summer or promoting mosaic–like mowing regimes, such as partial mowing, the quality of road verges as habitats for butterflies and diurnal moths can be improved. Key words: Mowing management, Road verge, Butterfly, Diurnal moth, Alternative habitat, Mowing intensity. Resumen Efecto de los distintos regímenes de siega de los márgenes de las carreteras sobre las polillas diurnas y las mariposas.— En Europa central y septentrional los márgenes de las carreteras constituyen hábitats alternativos para especies de invertebrados y plantas de los prados semi–naturales cuyas poblaciones se están reduciendo. -
