UK Butterflies - Orange- tip - Anthocharis cardamines. Introduction. The Orange- tip is a true sign of spring, being one of the first species to emerge that has not overwintered as an adult.

Japanese beetle (Popillia japonica) Family Scarabaeidae. The Japanese beetle (JB) is a serious. The male and female of this species are very different in appearance. The more- conspicuous male has orange tips to the forewings, that give this butterfly its name. These orange tips are absent in the female and the female is often mistaken for one of the other whites, especially the Green- veined White or Small White. This butterfly is found throughout England, Wales and Ireland, but is somewhat- local further north and especially in Scotland. In most regions this butterfly does not form discrete colonies and wanders in every direction as it flies along hedgerows and woodland margins looking for a mate, nectar sources or foodplants. More northerly colonies are more compact and also more restricted in their movements. Williams (1. 91. 6) disagrees with a particular aspect of the definition: . I have only two specimens agreeing exactly with the description.
Quoiqu'on rencontre des individus semblables . Although one finds individuals similar to those on the continent this local race merits the name Britannica. Chalmers- Hunt (1. Isle of Man, acknowledging that . This subspecies differs from the subspecies britannica as follows. It is slightly smaller although, according to Dennis (1. Huggins (pers. The black markings on the upperside fringes are more strongly marked. The underside forewing of the male is frequently tinged yellow although this is also, according to Dennis (1. Huggins (pers. The upperside hindwing of the female is strongly tinged yellow. According to Ford (1. It is figured in South (Butts. Any qualification of the name (e. Any UK BAP status is taken from the UK Biodiversity Action Plan (UK BAP) (2. Habitat. The species has a wide range of habitats which include country lanes, hedgerows, riverbanks, woodland margins and rides, and damp meadows. The species will also turn up in gardens. In exceptionally early years a small second brood may appear. The blue line gives average counts over the full data set from 1. Imago. Males are more- often noticed than females, largely due to the highly- visible orange splashes seen as the male butterfly flits along. It is believed that the orange tips of the male are an example of warning colouration, indicating that the butterfly is not particularly palatable to predators - a result of mustard oils that have accumulated in the body from the larval foodplant. The male is also the more- active of the two sexes as it searches out a mate and can be seen flying for long periods without ever stopping to rest or nectar. The female, on the other hand, is usually more concerned with egg- laying and, as a consequence, is often found in the vicinity of foodplants. Her more- secretive behaviour may also explain why she does not exhibit the warning colouration present in the male. When at rest on a flower head of the foodplant this butterfly so well camouflaged that an adult resting just a few feet away can easily be missed, even by an experienced observer. If the plant is suitable, a single egg is laid on a flower stalk. Eggs are laid singly for good reason - the larvae are cannibalistic. As a result, it is uncommon to find more than one egg per plant and it is believed that the female is able to detect eggs that have already been laid. However, the two species are not in competition since the Green- veined White eats the leaves of the plant, whereas the Orange- tip primarily feeds on the developing seed pods. The larva emerges after 1 or 2 weeks. The pupa is green when first formed, with the majority eventually turning light brown to more- closely match its surroundings. This species overwinters in this stage. Transactions of the Society for British Entomology. Dennis (1. 97. 7) Dennis, R. L. H. Entomologist's Gazette. Linnaeus (1. 75. 8) Linnaeus, C. Edition 1. 0.

Northern White Rhino Dies, Leaving Just 3 on the Planet. The extinction of the northern white rhino (Ceratotherium simum cottoni) draws ever closer. Nola, a 4. 1- year- old female that has lived at the San Diego Zoo Safari Park since 1. Nola had undergone surgery on Nov. The surgery was successful, but the zoo reports that Nola’s condition worsened over the past 2. With Nola’s death, there are now only three northern white rhinos left on the planet, all of which live at Ol Pejeta Conservancy in Kenya. The two remaining female rhinos are incapable of natural reproduction. The last surviving male, Sudan, has a very low sperm count but the conservancy still has hopes for in vitro fertilization. San Diego Zoo recently set aside $2 million as part of an effort to keep the species from going extinct by implanting northern white rhino embryos into surrogates from the related southern white rhino subspecies (C. That plan may still come to fruition, as the zoo has a collection of suitable genetic material in its Frozen Zoo. Northern white rhinos went extinct in the wild after years of extensive poaching for their valuable horns, which are used in traditional Asian medicine. The last wild northern white rhinos were killed in the Democratic Republic of the Congo in 2. Nola is being eulogized today on Twitter under the hashtag #Nola. Ever. Photo: San Diego Zoo Global.
