Agalmatium flavescens is a species of planthopper belonging to the family Issidae, subfamily Issinae. [2]
This species is present in Albania, Armenia, Austria, Bulgaria, France, Georgia, Greece, Hungary, Italy, Moldova, Montenegro, Portugal, Romania, Russia, Serbia, Slovenia, Spain and Turkey. [3] [4]
Agalmatium flavescens can reach a body length of approximately 4.5–5 millimetres (0.18–0.20 in) in males, of 5.3–6 millimetres (0.21–0.24 in) in females. [5] These planthoppers are characterized by a rather variable coloration. There are light specimens with a straw coloration, and light brownish specimens, with dark brown markings. The border of the forewings is always yellowish. Apical tube in males shows apically two distinct lobes. [5]
Like all species of the genus, the first segment of hind legs (metatarsomere) has only two intermediate spines apically. In the upper part of the forehead the horizontal transverse carinae are missing. The shape of the body is compact, the head is short and wide. Wings are rather developed, elytra are quite short. Legs are short and strong. [3]
This species is bivoltine, with two generations per year. Adults can be found from May to July and from Septembre to November. [6]
Recorded food plants are Ficus carica , Medicago sativa , Olea europea , Pinus species, Populus species, Prunus amygdalus and Tamarix species. [7]
It has been reported a trophobiotic association between this planthopper species and a species of ant ( Camponotus aethiops ), with honeydew drops directly collected by ants from the anal openings of these issids. [8]
The family Fulgoridae is a large group of hemipteran insects, especially abundant and diverse in the tropics, containing over 125 genera worldwide. They are mostly of moderate to large size, many with a superficial resemblance to Lepidoptera due to their brilliant and varied coloration. Various genera and species are sometimes referred to as lanternflies or lanthorn flies, though they do not emit light.
A planthopper is any insect in the infraorder Fulgoromorpha, in the suborder Auchenorrhyncha, a group exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and that they often "hop" for quick transportation in a similar way to that of grasshoppers. However, planthoppers generally walk very slowly. Distributed worldwide, all members of this group are plant-feeders, though few are considered pests. The infraorder contains only a single superfamily, Fulgoroidea. Fulgoroids are most reliably distinguished from the other Auchenorrhyncha by two features; the bifurcate ("Y"-shaped) anal vein in the forewing, and the thickened, three-segmented antennae, with a generally round or egg-shaped second segment (pedicel) that bears a fine filamentous arista.
Ant mimicry or myrmecomorphy is mimicry of ants by other organisms. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive. Spiders are the most common ant mimics. Additionally, some arthropods mimic ants to escape predation, while others mimic ants anatomically and behaviourally to hunt ants in aggressive mimicry. Ant mimicry has existed almost as long as ants themselves; the earliest ant mimics in the fossil record appear in the mid Cretaceous alongside the earliest ants. Indeed one of the earliest, Burmomyrma, was initially classified as an ant.
Coreus marginatus is a herbivorous species of true bug in the family Coreidae. It is commonly known as the dock bug as it feeds on the leaves and seeds of docks and sorrels. It is a medium-sized speckled brown insect, between 13 and 15 mm long as an adult, with a broad abdomen. It occurs throughout Europe, Asia and northern Africa. It is often found in dense vegetation, such as hedgerows and wasteland.
Acanalonia is a genus of planthopper in the fulgorid family Acanaloniidae.
Flatidae are a family of fulgoroid planthoppers. They are cosmopolitan in distribution and are distinguished from others in the superfamily by a combination of characters. Like all other planthoppers, they suck phloem sap of plants. Some species are known to communicate with vibrations through the plant stems. Communication may be with mates, or with ants that tend the nymphs, protecting them and gathering honeydew secretions. Adults of some species have brightly coloured forewings which are tougher and known as tegmina unlike the membranous hindwings which are used for flight. Although a few can be identified by their coloration, most species requires dissection and examination under a microscope with access to literature on already described species.
Enchophora sanguinea is a species of lantern bug, a type of hemipteran, found in Central and South America. It was first described by William Lucas Distant in 1887. They are 25 millimetres (1.0 in) long. Their colour varies, but is normally red to green; they have a scimitar-shaped process on their heads. They feed on the sap of trees, most commonly Simarouba amara, and they excrete honeydew out of their anuses.
Glisachaemus is an extinct monotypic genus of planthopper in the Cixiidae subfamily Cixiinae and at present, it contains the single species Glisachaemus jonasdamzeni. The genus is solely known from the Early Eocene Baltic amber deposits in the Baltic Sea region of Europe.
Issidae is a family of planthoppers described by Spinola in 1839, belonging to the order Hemiptera, suborder Auchenorrhyncha superfamily Fulgoroidea.
Ordralfabetix is an extinct genus of planthoppers in the family Lophopidae and containing the single species Ordralfabetix sirophatanis. The species is known only from the Early Eocene, Ypresian stage Oise amber from the Quesnoy locality, Oise Department, France.
Issus coleoptratus is a species of planthopper belonging to the family Issidae.
Acropyga glaesaria is an extinct species of ant in the subfamily Formicinae known from a group of possibly Miocene fossils found on Hispaniola. A. glaesaria is the first species of the ant genus Acropyga to have been described from fossils found in Dominican amber and is the one of several species of Acropyga found in the West Indies. As with other members of the genus, A. glaesaria was most likely trophobiotic.
Neoptychodes trilineatus is a species of flat-faced longhorn beetles in the subfamily Lamiinae.
Anochetus exstinctus is an extinct species of ant in the subfamily Ponerinae known from two possibly Miocene fossils found on Hispaniola. A. exstinctus is one of eight species in the ant genus Anochetus to have been described from fossils found in Dominican amber and is one of a number of Anochetus species found in the Greater Antillies.
Anochetus lucidus is an extinct species of ant in the subfamily Ponerinae known from two possibly Miocene fossils found on Hispaniola. A. lucidus is one of eight species in the ant genus Anochetus to have been described from fossils found in Dominican amber and is one of a number of Anochetus species found in the Greater Antillies.
Myrmecia regularis is a species of ant endemic to Australia. A member of the genus Myrmecia in the subfamily Myrmeciinae, it was first described by American entomologist Walter Cecil Crawley in 1925. These ants are medium to large in size, measuring 10 to 20 millimetres, and they are bright brownish-red in colour. Queens and workers share similar morphological features, but they can be distinguished by the noticeable size difference. Males also look similar, but collected specimens are too damaged to be examined properly.
Bythopsyrna circulata is a species of Asian planthoppers belonging to the family Flatidae.
The black-headed sugar ant, also known as the brown sugar ant, is a species of Formicinae ant endemic to Australia. Found throughout most states, the species is a member of the genus Camponotus, a cosmopolitan genus of ants commonly known as carpenter ants. It was formally described and named by British entomologist Frederick Smith in 1858. These ants are characterised by their black head, reddish-brown mesosoma and black gaster, which can change in colour.
Agalmatium is a genus of planthoppers belonging to the family Issidae, subfamily Issinae.
Dundubia is a genus of cicadas in the subfamily Cicadinae and the type genus of the tribe Dundubiini.
