Sexual Selection In Social Insects
Sexual selection in insects is about how sexual selection functions in insects. The males of some species have evolved exaggerated adornments and mechanisms for self-defense. These traits play a role in increasing male reproductive expectations by triggering male-male competition or influencing the female mate choice, and can be thought of as functioning on three different levels: individuals, colonies, and populations within an area. Male mating tactics The amount of space accessible and the time both male and female usually determines the site of copulation. Many hymenopteran males constantly fly around specific sites, usually the tops of tall trees, summits, or along hedges, where approachable females are found as they can also be resources visited by females for the purpose of feeding. In honey bee the queens join the mating area alone and are then pursued by a dynamic Swarm behaviour, swarm of males. Those located in the front of the line usually achieve reproduction succes ...

Green-veined White
The green-veined white (''Pieris napi'') is a butterfly of the family Pieridae. Appearance and distribution A Circumboreal Region, circumboreal species widespread across Europe and Asia, including the Indian subcontinent, Japan, the Maghreb and North America. It is found in meadows, hedgerows and woodland glades but not as often in gardens and parks like its close relatives the large and small whites, for which it is often mistaken. Like other "Pieridae, white" butterflies, the sexes differ. The female has two spots on each forewing, the male only one. The veins on the wings of the female are usually more heavily marked. The underside hindwings are pale yellow with the veins highlighted by black scales giving a greenish tint, hence green-veined white. Unlike the large and small whites, it rarely chooses garden cabbages to lay its eggs on, preferring wild Brassicaceae, crucifers. Males emit a sex pheromone that is perceptible to humans, citral, the basic flavor-imparting component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Firefly
The Lampyridae are a family of elateroid beetles with more than 2,000 described species, many of which are light-emitting. They are soft-bodied beetles commonly called fireflies, lightning bugs, or glowworms for their conspicuous production of light, mainly during twilight, to attract mates. The type species is '' Lampyris noctiluca'', the common glow-worm of Europe. Light production in the Lampyridae is thought to have originated as a warning signal that the larvae were distasteful. This ability to create light was then co-opted as a mating signal and, in a further development, adult female fireflies of the genus '' Photuris'' mimic the flash pattern of the '' Photinus'' beetle to trap their males as prey. Fireflies are found in temperate and tropical climates. Many live in marshes or in wet, wooded areas where their larvae have abundant sources of food. Although all known fireflies glow as larvae, only some species produce light in their adult stage, and the location ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photuris Lucicrescens
''Photuris lucicrescens'', the long crescendo ''Photuris'', July comet, big scary, or big Lucy, is a species of beetle in the Lampyridae family. It is found in the eastern United States. Description ''P. lucicrescens'' is a large firefly, with adults measuring long. They appear to be hunchbacked when viewed from the side. They have brown wing covers, or elytra, with wide light-colored side margins and stripes in the center of each side, starting from the shoulder and extending almost the entire length of the body. The head shield, or pronotum, is yellow, with a dark arrow in the center, which is often interrupted, appearing as two separate marks. The dark central mark is bounded by red or orange. ''Photuris'' fireflies have longer legs than species in the other common firefly genus in the United States, ''Photinus''. The legs are pale close to the body. Lanterns are visible on the abdomen as pale segments. Etymology ''Photuris'' has its origins in the Greek words for light, "ph ...

Panorpa Japonica
''Panorpa japonica'', the common Japanese scorpionfly, is recognized for its translucent wings with two black bands. It has a sleek, entirely black body and a distinctive curved snout as long as its thorax. Its long, thread-like black antennae nearly match the length of its body. It is a species from the genus ''Panorpa''. It was originally described by Carl Peter Thunberg in 1784. Females of ''Panorpa japonica'' prefer the pheromone of males with low fluctuating asymmetry of the forewing.Thornhill, R. (1992). Female preference for the pheromone of males with low fluctuating asymmetry in the Japanese scorpionfly (Panorpa japonica: Mecoptera). Behavioral Ecology, 3(3), 277–283. https://doi.org/10.1093/BEHECO/3.3.277 Low fluctuating asymmetry frequently correlates with individual fitness components such as growth, fecundity or survival. Thus female choice of mate should produce more fit offspring than random mating. Distribution ''Panorpa japonica'' has primarily been observed i ...

Predation
Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey. It is one of a family of common List of feeding behaviours, feeding behaviours that includes parasitism and micropredation (which usually do not kill the Host (biology), host) and parasitoidism (which always does, eventually). It is distinct from Scavenger, scavenging on dead prey, though many predators also scavenge; it overlaps with Herbivore, herbivory, as Seed predation, seed predators and destructive frugivores are predators. Predation behavior varies significantly depending on the organism. Many predators, especially carnivores, have evolved distinct hunting strategy, hunting strategies. Pursuit predation involves the active search for and pursuit of prey, whilst ambush predation, ambush predators instead wait for prey to present an opportunity for capture, and often use stealth or aggressive mimicry. Other predators are opportunism, opportunistic or om ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utetheisa Ornatrix
''Utetheisa ornatrix'', also called the ornate bella moth, ornate moth, bella moth or rattlebox moth, is a moth of the subfamily Arctiinae. It is aposematically colored ranging from pink, red, orange and yellow to white coloration with black markings arranged in varying patterns on its wings. It has a wingspan of 33–46 mm. Moths reside in temperate midwestern and eastern North America as well as throughout Mexico and other parts of Central America. Unlike most moths, the bella moth is diurnal. Formerly, the bella moth or beautiful utetheisa of temperate eastern North America was separated as ''Utetheisa bella''. Now it is united with the bella moth in ''Utetheisa ornatrix''. The larvae usually feed on ''Crotalaria'' species, which contain poisonous alkaloid compounds that render them unpalatable to most predators. Larvae may prey on other bella moth larvae in order to compensate for any alkaloid deficiency. The bella moth also demonstrates complex mating strategies and is ...

Queen (butterfly)
The queen butterfly (''Danaus gilippus'') is a North and South American butterfly in the family Nymphalidae with a wingspan of . It is orange or brown with black wing borders and small white forewing spots on its Dorsum (biology), dorsal wing surface, and reddish ventral wing surface fairly similar to the dorsal surface. The ventral hindwings have black veins and small white spots in a black border. The male has a black androconial scent patch on its dorsal hindwings. It can be found in meadows, fields, marshes, deserts, and at the edges of forests. This species is possibly a close relative to the similarly colored soldier butterfly (or tropical queen, ''Danaus eresimus, D. eresimus''), in any case, it is not close to the plain tiger (''Danaus chrysippus, D. chrysippus'', African queen) as was long believed. There are seven subspecies. Females lay one egg at a time on larval host plants. Larvae use these plants as a food source, whereas adult butterflies feed mainly on nectar fro ...

Pheromone
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm signal, alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek language, Greek () and (). Pheromones are also sometimes classified as ec ...

Spider
Spiders (order (biology), order Araneae) are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude spider silk, silk. They are the largest order of arachnids and rank seventh in total species diversity among all Order (biology), orders of organisms. Spiders are found worldwide on every continent except Antarctica, and have become established in nearly every land habitat. , 53,034 spider species in 136 Family (biology), families have been recorded by Taxonomy (biology), taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomy, Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segmentation (biology), segments are fused into two Tagma (biology), tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindr ...

Scorpion
Scorpions are predatory arachnids of the Order (biology), order Scorpiones. They have eight legs and are easily recognized by a pair of Chela (organ), grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back Silurian, 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their Taxonomy (biology), taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The Scorpion sting, venomous sting is used for offense and defense. During courtship, the male and female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
