Ankothrips yuccae is a species of thrip in the family Melanthripidae. [1] Its host plant is Yucca whipplei . [2]
Both sexes are winged, with light brown to brown body, legs and antennae, with antennal segments 3-4 paler and forewings fuscous with its base a little bit paler. Its antennae has nine segments, the ninth longer the eight, sensoria transverse on the third- fourth, the second segment apex prolonged ventro-laterally into serrate lobe. Head with ocellar setae I arising on conical, slightly bifurcate tubercle, the third setae arise within ocellar triangle. It hears with 3 pairs of prominent postocular setae and the pronotum posterior margin with 5 pairs of prominent setae. Mesonotum has microtrichia, Metanotum striate medially, with median setae near posterior margin. The 8th abdominal tergite median setae scarcely 0.3 as long as tergite; tergite 10 with paired trichobothria well developed. Sixth sternite posterior margin with pair of lobes each bearing two setae at base. [2]
Ankothrips yuccae breeds on Yucca whipplei without leaving major harm in California. It has no known vectors. [2]
The Phoridae are a family of small, hump-backed flies resembling fruit flies. Phorid flies can often be identified by their escape habit of running rapidly across a surface rather than taking to the wing. This behaviour is a source of one of their alternate names, scuttle fly. Another vernacular name, coffin fly, refers to Conicera tibialis. About 4,000 species are known in 230 genera. The most well-known species is cosmopolitan Megaselia scalaris. At 0.4 mm in length, the world's smallest fly is the phorid Euryplatea nanaknihali.
This glossary of entomology describes terms used in the formal study of insect species by entomologists.
Gangara lebadea, the banded redeye, is a species of hesperid butterfly found in Southeast Asia.
Cherax parvus is a species of crayfish in the family Parastacidae. It is only known from its type locality – the Upper Tully River catchment in the Cardwell Range of north-eastern Queensland – and is listed as data deficient on the IUCN Red List. It was discovered in a rainforest catchment in a highland of northeastern Queensland during a Queensland Museum expedition to the upper Tully River area in November 1992. It is one of the smallest species in the genus. No species of Cherax has been considered endemic to wet upland or highland areas before it was discovered; most previous records were from elevations less than 400 meters. It also has several morphological features unique to the genus, and does not appear closely related to any extant species, suggesting a long period of geographic isolation.
Micropterix aglaella is a species of moth belonging to the family Micropterigidae.It is found in southern France, south-western Switzerland and northern Italy.
Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insects from other arthropods: they have a body divided into three regions, have three pairs of legs, and mouthparts located outside of the head capsule. It is this position of the mouthparts which divides them from their closest relatives, the non-insect hexapods, which includes Protura, Diplura, and Collembola.
Leptostylopsis annulipes is a species of longhorn beetles of the subfamily Lamiinae.
Cebrionini is a tribe of click beetles from the family Elateridae; formerly ranked as a subfamily or family, they are now considered a tribe within the subfamily Elaterinae.
Dipteran morphology differs in some significant ways from the broader morphology of insects. The Diptera is a very large and diverse order of mostly small to medium-sized insects. They have prominent compound eyes on a mobile head, and one pair of functional, membraneous wings, which are attached to a complex mesothorax. The second pair of wings, on the metathorax, are reduced to halteres. The order's fundamental peculiarity is its remarkable specialization in terms of wing shape and the morpho-anatomical adaptation of the thorax – features which lend particular agility to its flying forms. The filiform, stylate or aristate antennae correlate with the Nematocera, Brachycera and Cyclorrhapha taxa respectively. It displays substantial morphological uniformity in lower taxa, especially at the level of genus or species. The configuration of integumental bristles is of fundamental importance in their taxonomy, as is wing venation. It displays a complete metamorphosis, or holometabolous development. The larvae are legless, and have head capsules with mandibulate mouthparts in the Nematocera. The larvae of "higher flies" (Brachycera) are however headless and wormlike, and display only three instars. Pupae are obtect in the Nematocera, or coarcate in Brachycera.
Porcellio formosus is a species of woodlouse in the genus Porcellio belonging to the family Porcellionidae that can be found in San Pedro and San Francisco of California.
Zigrasimecia is an extinct genus of ants which existed in the Cretaceous period approximately 98 million years ago. The first specimens were collected from Burmese amber in Kachin State, 100 kilometres (62 mi) west of Myitkyina town in Myanmar. In 2013, palaeoentomologists Phillip Barden and David Grimaldi published a paper describing and naming Zigrasimecia tonsora. They described a dealate female with unusual features, notably the highly specialized mandibles. Other features include large ocelli, short scapes, 12 antennomeres, small eyes, and a clypeal margin that has a row of peg-like denticles. The genus Zigrasimecia was originally incertae sedis within Formicidae until a second species, Zigrasimecia ferox, was described in 2014, leading to its placement in the subfamily Sphecomyrminae. Later, it was considered to belong to the distinct subfamily Zigrasimeciinae.
Pristomyrmex tsujii is a species of ant in the genus Pristomyrmex. Known from Fiji, where they are widely distributed but rarely encountered. The species has a discrete ergatoid queen caste that is intermediate between a worker and an alate queen.
Plutonium zwierleini, in the monotypic genus Plutonium, is one of the largest scolopendromorph centipedes in Europe, and one of the few potentially harmful to humans. Nevertheless, it has been rarely reported, only from the southern part of the Iberian and Italian peninsulas, Sardinia and Sicily.
Bucolus fourneti is a native Australian, small, hairy coccinellid beetle approximately 2.1-4.5 mm in diameter. It was described by Étienne Mulsant in 1850
Brachyopa flavescens, The Yellow Sapeater, is a fairly common species of syrphid fly. It has been observed in northeastern North America. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae for this genus are of the rat-tailed type. B.flavescens larvae have not been described.
Blera flukei, the Red-cheeked Wood Fly, is a rare species of syrphid fly first officially described by Curran, 1953 as Cynorhina flukei. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. The larvae are of the rat-tailed type, feeding on exuding sap or in the rot holes of trees.
Armadillidium maniatum is a European species of woodlouse endemic to Greece.
Sphegina (Asiosphegina) adusta is a species of hoverfly in the family Syrphidae found in Myanmar. It's easily identified by its large size, left side surstylus with a number of unusual lobes, and general dark-brown coloration. It's similar to S. atricolor and S. furva, but unlike these species it lacks a transverse crest at the base of the lobe located sinistrolaterally at the posterior margin of male sternite IV.
Brachyopa caesariata, the Plain-winged Sapeater, is an uncommon species of syrphid fly. It has been observed in Canada, Alaska and northern United States. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae for this genus are of the rat-tailed type. B.caesariata larvae have not been described.
Brachyopa diversa , the Pale-striped Sapeater, is a rare species of syrphid fly. It has been observed in the northeastern part of North America. Hoverflies get their names from the ability to remain nearly motionless while in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen. Larvae for this genus are of the rat-tailed type. B.diversa larvae have not been described.
