It can also be noted that the hoverfly resting on the flower exhibits Batesian mimicry , copying the yellow black warning coloration of a yellowjacket wasp which was designed to advertise the wasp s potential to cause harm. Advertising coloration or advertising colouration refers to semantic color colour s seen in numerous organisms. It is the opposite of camouflage , advertising the location of an organism or part of its anatomy. These signals are significant for their receivers. In the case of warning coloration, a form of aposematism , they function to make harmful organisms more distinct from prey that are safe to eat.

It is found only in Italy . Its natural habitat s are temperate forest s, river s, and freshwater marsh es. It is threatened by habitat loss . This species is found only in the Apennine Range in humid valleys and shady, overgrown hillsides at altitudes between 200m and 1,200m. It is considered an important indicator species of environmental health. It has 4 toes on the hind feet rather than the 5 normally found in other salamanders and newts. It has a warty, brownish black back, and a rather ribbed appearance on its flanks, with a creamy white, V shaped mark between the eyes. The underside is covered in black and white markings, with pinkish red underside to legs and tail. The Spectacled Salamander is most often found near streams, in dense vegetation, under leaf litter, dead wood or stones. It is nocturnal and terrestrial. s. When threatened, it raises its tail and legs unkenreflex , displaying its red underside as a deterrent. Similar warning displays aposematism is shown by newts , the Apennine Yellow bellied Toad and the Spotted Salamander . Mating takes place on land in spring. Clutches contain about 30 50 eggs and the larvae take 2 3 months to develop.

dablink This article is about the structure in insects. For the musical instrument, see Timbal . Tymbal or timbal is a term for a corrugated exoskeleton exoskeletal structure used to produce sounds in insects. In male cicada s, the tymbals are membranes in the abdomen, responsible for the characteristic sound produced by the insect. In tiger moth s, the tymbals are modified regions of the thorax , and produce high frequency clicks. The paired tymbals of a cicada are located on the sides of the abdomen abdominal base. The singing of a cicada is not stridulation as in many other familiar sound producing insects like cricket insect crickets where one structure is rubbed against another the tymbals are regions of the exoskeleton that are modified to form a complex membrane with thin, membranous portions and thickened ribs . These membranes vibrate rapidly, and enlarged chambers derived from the Invertebrate trachea tracheae make the cicada s body serve as a resonance chamber, greatly amplifying the sound. Some cicadas produce sounds louder than 106 dB SPL , among the loudest of all insect produced sounds. They modulate their noise by positioning their abdomens toward or away from the substrate. The tymbals of a tiger moth are specialized regions on the metathorax metathoracic episternum episterna , normally corrugated such that sound is produced when the entire tymbal surface is buckled by muscular contraction and then released, producing a series of extremely rapid clicks as the corrugations flex back into place ref J.H.

The soft, brightly red body is covered with fine hairs, giving it a velvety appearance. The small eyes are located on stalks. They have scissor like chelicera e, their pedipalp s are used as touch organs. Its bright red color results from carotenoid s, warning predator s about the toxicity of the mite aposematism . Almost nothing is known about the toxic substances used, but they are probably contained within the integument . The specific name zoology specific epithet is derived from Ancient Greek lang el holo whole and lang el seric silken . Biology While adults live freely and are often found wandering about, searching for small animals and insect eggs for food, the larva e try to find a host to attach themselves to, often an insect like a grasshopper or diptera diptere , but also arachnids like harvestmen or spider s. At this stage they are seen as red globules on their hosts, sucking body liquid without severely harming the host. These larvae then develop into free living nymph s that resemble adults.

The vernacular name derives from the repeated metallic tink, tink, tink alarm call, which suggests a blacksmith s hammer striking an anvil. Description Blacksmith Lapwings are very boldly patterned in black, grey and white, possibly Aposematism warning colours to predators. It is one of five lapwing species two African, one Asian and two Neotropical that share the characteristics of a carpal wing spur, red eye and a bold pied plumage. The bare parts are black. Females average larger and heavier but the sexes are generally alike. Habitat and numbers The Blacksmith Lapwing occurs in association with wetlands of all sizes. Even very small damp areas caused by a spilling water trough can attract them. In South Africa they are most numerous in the Mesic habitat mesic grassland region, less so in higher rainfall grasslands. Like the Crowned Lapwing , this species may leave Zambia and Zimbabwe in years of high rainfall and return in dry years. It avoids mountains of any type. Blacksmith Lapwings expanded their range in the 20th century into areas where dams were built and where intensive farming was practiced. Consequently they are now numerous and established in the western Cape region of South Africa, where they were absent until the 1930s.
