Trombidium Breei
''Trombidium breei'' is a species of red mite in the genus ''Trombidium'' in the family Trombidiidae. It is found in Europe. The larvae are parasites/hosts of certain butterflies ( Lepidoptera), particularly meadow brown (''Maniola jurtina''), gatekeeper (''Pyronia tithonus''), marbled white (''Melanargia galathea''), common blue (''Polyommatus icarus'') and small skipper (''Thymelicus sylvestris The small skipper (''Thymelicus sylvestris'') is a butterfly of the family Hesperiidae.

Ronald Vernon Southcott
Ronald Vernon Southcott (15 May 1918 in Adelaide – 9 April 1998) was an Australian medical zoologist specializing in Acari, mites and ticks. Biography After finishing school at St Peter's College, Adelaide Southcott started working on mites, or the acari, at the age of 16 with Herbert Womersley the acarologist at the South Australian Museum. Womersley described and named the trombidiid mite, which Southcott had collected on a cycling trip in the hills near Adelaide in 1934, '' Microtrombidium southcotti'', after Southcott. Southcott considered that act by Herb Womersley, "hooked me on mites". Southcott studied medicine at the University of Adelaide where he graduated in 1941. Southcott then served in the Australian Army Medical Corps from 1942 to 1946. While he was stationed at Cairns he started working on the taxonomy and medical effects of jellyfish, the subject for which he was later to become famous. His more than 230 papers on the red mites include a classic revision of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mite
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are predators or parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two distinct groups of arachnids ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trombidiidae
Trombidiidae, also known as red velvet mites, true velvet mites, or rain bugs, are small arachnids (eight-legged arthropods) found in plant litter and are known for their bright red color. While adults are typically in length, some, such as the genus ''Dinothrombium'', may reach up to . Their life pattern is in stages similar to other members of the Prostigmata: egg, pre-larva, larva, protonymph, deutonymph, tritonymph and adult (male or female). They usually have only one breeding cycle per year.Zhang, Zhi-Qiang (1998) Biology and ecology of trombidiid mites (Acari: Trombidioidea) Experimental & Applied Acarology 22:139–15PDF/ref> They are active predators as grown adults. As early instars they are often parasites of insects and other arachnids. One well known species from Europe, Asia, and North Africa is ''Trombidium holosericeum''. The systematics of this group has been in flux and many former subfamilies of this are now raised to families within the Trombidioidea. L ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are im ...

Parasitism
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson has characterised parasites as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), Disease vector, vector-transmitted paras ...

Lepidoptera
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
