Brimstone Butterfly– one of the few UK butterflies which overwinter as adults, I’ve been watching this beautiful female which will have emerged from eggs laid by the overwintering generation. They will be around feeding all autumn, building up for their hibernation. Opinion is divided as to whether the colour of the much more yellow male of this species (see other photo) gave rise to the generic name of ‘butter’-fly, but male and female are both beautiful and distinctly shaped. The caterpillars rely on buckthorn and alder buckthorn so please grow either in your patch if you can (Can be bought from Ashridge Nurseries mail order) Conditions– sunny intervals. Temperature: Max 20- Min 11C.
Small Copper: We are lucky to have this small. bright, active butterfly in our garden sometimes, especially this year on the Marjoram. Present in many areas, in small colonies, they move fast, flashing orange/copper and are best identified when settled. Males aggressively hold territories, basking on bare ground or stones, and chasing off any approaching insects, before resettling on the same spot. Loving unimproved grassland, a declining habitat, it isn’t surprising that their numbers are sadly declining, too. Conditions: Sun and showers. Temperature: Max 21- Min 10C.
Male Sparrowhawk– Yesterday the grey-backed, smaller male Sparrowhawk (the female and juveniles are brown-backed) was heralded in the garden by loud alarm calls from other birds. Sweeping through the garden, too fast to photograph, here it is recently, looking dapper, and an older photo by Lynn, where it is eating a Collared Dove. No one is certain why many raptors exhibit ‘reverse dimorphism’ (meaning the males are smaller than the females) but it it is thought to relate to their need to be very manouevrable in dense woodland, hunting for the incubating female
, and/or the female’s need to have enough bulk to produce eggs. Conditions: Cloud and sunny intervals and showers Temperature: Max 20- Min 12C.
Greenfinches have declined so much since the 1990′s that we have felt lucky to have a family of adults and two young, visiting our feeders, enjoying their favourite black sunflower-seeds. Originally woodland birds, they have now been drawn to gardens, but suffer from the parisitic-induced disease ‘trichomonosis’, which affects their ability to feed- the advice is to make sure your feeders are frequently cleaned. Young have the same yellow edge to their wings and tail as adults but have streaky chests, visible here. Greenfinches will also feast on Rose-hips, Haws, and Yew Berries
Conditions: Cloud and sun, with rain later. Temperature: Max 20- Min 13C.
Rowan berries provide high energy food for many in the Thrush family, including this female Blackbird stripping our tree. Mountain Ash/ Rowan was thought by the ancient Greeks to represent an eagle battling evil, the leaves recalling the feathered eagle-wings and the red berries, spots of shed blood. In Scotland it was widely planted beside houses to ward off evil and witches. The hard wood has been used for divining rods, spinning wheels and tool handles while pieces of wood were carried as charms against rheumatism. The flowers feed many insects and the
An all-round great plant for wildlife. Conditions: Rain, sun and cloud. Temperature: Max 18- Min 13C.
At this time of year no plant in our Sheffield city garden feeds more Butterflies and Bees than Marjoram, which spreads easily but is easy to control. Just right for taking part in the Butterfly Conservation 15 minute Butterfly Count– easy to download an app- with an identification guide if you need it. This week it attracted a (tattered) Ringlet, the first one we have seen here, and a favourite Gatekeeper, as well as the Small Skipper. Conditions: Cloudy with sunny spells. Temperature: Max 20- Min 15C.
The small, beautiful Holly Blue butterfly, the only blue we get in our garden and the one you are most likely to see in parks and gardens in England and Wales, flitting low and fast, is back feeding on our flowers. Numbers of Holly Blue fluctuate greatly, thought to be due to the variable numbers of the parasitic wasp which lays its eggs in their caterpillars. The caterpillars feed on holly as the name suggests, but also on dogwood, spindle, snowberry and other common bushes. The female has a dark edge to the wing. Conditions: cloudy after heavy rain. Temperature: Max 19- Min 13 C.
