The goldenrod soldier beetle [1] or Pennsylvania leatherwing [2] (Chauliognathus pensylvanicus) is a species of soldier beetle (Cantharidae).
The specific epithet pensylvanicus is Latin for "of Pennsylvania". The spelling with one n was in common use at the time (de Geer says in the description that the specimen was sent to him from 'Pensylvanie'), so the species name based on it cannot be corrected under the rules governing scientific names. [1]
The species is native to North America, and is one of the most common species of soldier beetle in the Midwest. [3]
C. pensylvanicus has been identified as an important pollinator of the prairie onion. [4] Adults of the species are active in late summer and early fall. The beetle prefers yellow flowers. [5]
Adult C. pensylvanicus may be infected by the fungus Eryniopsis lampyridarum . After the fungus infects the host, it takes about two weeks for it to eventually kill its host. Before the host dies, the fungus orders the beetle to climb a plant and then attach itself to a flower by biting down with its mandibles into flower heads. [6] About 15–22 hours later, the fungus causes the dead beetles to raise their elytra and expand their metathoracic wings in order to maximise infection of other beetles. [7] With their wings raised, the dead beetles may still attract mates as live males were observed mating with the deceased, infected females, this then transmits spores from one insect-host to another. [8]
Beetles are insects that form the order Coleoptera, in the superorder Holometabola. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal species; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.
The soldier beetles (Cantharidae) are relatively soft-bodied, straight-sided beetles. They are cosmopolitan in distribution. One of the first described species has a color pattern reminiscent of the red coats of early British soldiers, hence the common name. They are also known commonly as leatherwings because of their soft elytra.
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described.
The tansy beetle is a species of leaf beetle. The common name derives from its main foodplant, Tansy, but it can also use other wetland plants such as Gypsywort and Water Mint. It measures 7.7–10.5 mm in length and has a characteristic bright metallic green colouration, with pitted elytra and a coppery tinge. In addition to the nominotypical subspecies, which repeats the specific name, C. graminis graminis, there are five further distinct subspecies of Tansy beetle, which, collectively, have a Palearctic distribution, although in the majority of countries where it is found the species is declining. In the United Kingdom it is designated as 'Nationally Rare'. The stronghold population here is located along the banks of the river Ouse in York, North Yorkshire. Other, small, fenland populations exist at Woodwalton Fen and at Welney Wildfowl and Wetlands Trust (WWT) reserve.
Rhagonycha fulva, the common red soldier beetle, also misleadingly known as the bloodsucker beetle, and popularly known in England as the hogweed bonking beetle is a species of soldier beetle (Cantharidae).
Massospora cicadina is a fungal pathogen that infects only 13 and 17 year periodical cicadas. Infection results in a "plug" of spores that replaces the end of the cicada's abdomen while it is still alive, leading to infertility, disease transmission, and eventual death of the cicada.
Bombus pensylvanicus, the American bumblebee, is a threatened species of bumblebee native to North America. It occurs in eastern Canada, throughout much of the Eastern United States, and much of Mexico.
Echinocystis is a monotypic genus in the gourd family, Cucurbitaceae. The sole species is E. lobata, commonly called wild cucumber, prickly cucumber or bur cucumber. It is an annual, sprawling plant that is native to North America.
Chauliognathus is a genus of soldier beetles in the family Cantharidae. Adults have almost rectangular bodies. Some are red and black, similar to the military uniforms that were common before the usage of camouflage, hence the name of soldier beetles. Others are orange and black. The elytra or first pair of wings are softer than the elytra of most beetles, that is why their other common name is leatherwings. The adults are frequently found on flowers, such as sunflowers, goldenrod, coneflowers, where they mate and feed on pollen and nectar. The larvae are more common in the ground or among debris, where they feed on eggs or larvae of other insects. The adults are most frequently found in summer and early fall. They are native to America and Australia.
Chauliognathus lugubris, the plague soldier beetle, green soldier beetle or banana bug, is a species of soldier beetle (Cantharidae) native to Australia. It has a flattened body to 15 millimetres (0.59 in) long with a prominent yellow-orange stripe behind the black prothorax. The abdomen is yellow-orange but is mostly obscured by the metallic olive green elytra.
Blastophaga psenes is a wasp species in the genus Blastophaga. It pollinates the common fig Ficus carica and the closely related Ficus palmata. Without a colony or nest, these wasps breed in figs and the adults live for only a few days or weeks. They locate the fig they wish to pollinate through olfactory senses.
Ecological speciation is a form of speciation arising from reproductive isolation that occurs due to an ecological factor that reduces or eliminates gene flow between two populations of a species. Ecological factors can include changes in the environmental conditions in which a species experiences, such as behavioral changes involving predation, predator avoidance, pollinator attraction, and foraging; as well as changes in mate choice due to sexual selection or communication systems. Ecologically-driven reproductive isolation under divergent natural selection leads to the formation of new species. This has been documented in many cases in nature and has been a major focus of research on speciation for the past few decades.
Pollen beetle is an informal term for any species of beetle associated intimately with suitably pollen-rich species of flowers. Typically such a beetle is adapted to the pollen as a major part of its diet. Species in at least sixteen families of the order Coleoptera could be counted as pollen beetles, and "pollen beetle" also is a common name for some such species.
Euwallacea fornicatus is a species complex consisting of multiple cryptic species of ambrosia beetles, known as an invasive species in California, Israel and South Africa. The species has also been unintentionally introduced into exotic greenhouses in several European countries. As the rest of the ambrosia beetles, E. fornicatus larvae and adults feed on a symbiotic fungus carried in a specific structure called mycangium. In E. fornicatus, the mycangium is located in the mandible. The combination of massive numbers of beetles with the symbiotic fungus kills trees, even though the fungus alone is a weak pathogen.
Xylosandrus compactus is a species of ambrosia beetle. Common names for this beetle include black twig borer, black coffee borer, black coffee twig borer and tea stem borer. The adult beetle is dark brown or black and inconspicuous; it bores into a twig of a host plant and lays its eggs, and the larvae create further tunnels through the plant tissues. These beetles are agricultural pests that damage the shoots of such crops as coffee, tea, cocoa and avocado.
Eryniopsis lampyridarum is an entomopathogenic fungus and its host is the soldier beetle, either Chauliognathus marginatus or Chauliognathus pensylvanicus.Eryniopsis lampyridarum is mind controlling for the soldier beetle and can manipulate the beetle into doing things that it wouldn't normally do. Once the fungus has established itself inside the beetle, it sends the infected beetle on a mission to find a specific daisy flower Asteraceae. The soldier beetle will clamp its mouthpiece onto the flower as tight as it can, while it awaits its death. The parasitic fungus forces the dead beetle to then spread its wings wide in a dramatic pose; this makes the beetle look bigger as if it is seeking out a mate. The fungus makes sure the dying beetle will attract more beetles so it can spread its spores. The fungus makes sure the beetle spreads its wings only at daybreak. It is also strange that the beetle will be dead for hours and then suddenly it will spread its wings at daylight, just in time to attract potential mates to its dead body. This is because the fungus is in control of the beetle's body functions. Then, when an uninfected beetle comes along to socialize with the dead beetle, the fungus' spores spread to the new beetle.
Chauliognathinae is a subfamily of soldier beetles in the family Cantharidae. There are at least 4 genera and at least 20 described species in Chauliognathinae.
Chauliognathus marginatus, known generally as the margined leatherwing or margined soldier beetle, is a species of soldier beetle in the family Cantharidae. It is found in Central America and North America. It is most commonly found on white flowers in spring and early summer. s
Zorion guttigerum, commonly known as the flower long-horn beetle, is an endemic species of beetle in New Zealand. It is found on the flowers of many plant species and feeds on nectar and pollen.
Eryniopsis is a genus of fungi within the family of Entomophthoraceae and order Entomophthorales of the Zygomycota. This has been supported by molecular phylogenetic analysis.
