Ilybius fenestratus
(Fabricius, 1781)

Ilybius fenestratus is a species of beetle found throughout Europe and Northern Asia. It was first described by Johan Christian Fabricius in 1781. [1]

The scent gland of this species of beetle is natural source for the anabolic steroid boldenone1-testosterone). [2]

Life cycle

A study conducted in Målsjøen found the life cycle of the species to be semivoltine, with adults emerging in midsummer. They hibernate over the winter, possibly in the water, the hibernation lasting until mid-June. Breeding takes place from mid- to late summer, the last adults dying in autumn. The larvae hatch in late summer and hibernate, in the water, until April to May, when they emerge from the water to pupate. [3]

The small tortoiseshell is a colourful Eurasian butterfly in the family Nymphalidae. Adults feed on nectar and may hibernate over winter; in warmer climates they may have two broods in a season. While the dorsal surface of the wings is vividly marked, the ventral surface is drab, providing camouflage. Eggs are laid on the common nettle, on which the larvae feed.

<span class="mw-page-title-main">Tansy beetle</span> Species of beetle

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.

The gray bat is a species of microbat endemic to North America. It once flourished in caves all over the southeastern United States, but due to human disturbance, gray bat populations declined severely during the early and mid portion of the 20th century. 95% of gray bats now hibernate in only 15 caves. M. grisescens has been listed as federally endangered by the U.S. Fish and Wildlife Service since 1976, and is protected under the Endangered Species Act. Gray bat populations were estimated at approximately 2 million bats around the time they were placed on the Endangered Species list. By the early 1980s populations of gray bats dropped to 1.6 million. With conservation efforts in place, in 2004, gray bat populations were estimated to have reached 3.4 million.

<span class="mw-page-title-main">Dytiscidae</span> Family of beetles

The Dytiscidae – based on the Greek dytikos (δυτικός), "able to dive" – are the predaceous diving beetles, a family of water beetles. They occur in virtually any freshwater habitat around the world, but a few species live among leaf litter. The adults of most are between 1 and 2.5 cm (0.4–1.0 in) long, though much variation is seen between species. The European Dytiscus latissimus and Brazilian Megadytes ducalis are the largest, reaching up to 4.5 and 4.75 cm respectively. In contrast, the smallest is likely the Australian Limbodessus atypicali of subterranean waters, which only is about 0.9 mm (0.035 in) long. Most are dark brown, blackish, or dark olive in color with golden highlights in some subfamilies. The larvae are commonly known as water tigers due to their voracious appetite. They have short, but sharp mandibles and immediately upon biting, they deliver digestive enzymes into prey to suck their liquefied remains. The family includes more than 4,000 described species in numerous genera.

Ripiphoridae is a cosmopolitan family of some 450 described species of beetles sometimes called "wedge-shaped beetles". Ripiphoridae are unusual among beetle families in that many species are hypermetamorphic parasitoids, an attribute that they share with the Meloidae. Members of the family differ in their choice of hosts, but most attack various species of bees or wasps, while some others attack cockroaches or beetles. Many species of Ripiphoridae have abbreviated elytra, and flabellate or pectinate antennae.

The meadow jumping mouse is the most widely distributed mouse in the family Zapodidae. Its range extends from the Atlantic coast in the east to the Great Plains west, and from the arctic tree lines in Canada and Alaska to the north, and Georgia, Alabama, Arizona, and New Mexico to the south. In mid-2014, the New Mexico subspecies of the meadow jumping mouse, Zapus hudsonius luteus, was listed as an endangered species under the federal Endangered Species Act.

<i>Coccotrypes dactyliperda</i> Species of beetle

Coccotrypes dactyliperda, the date stone beetle, palm seed borer, or button beetle, is an insect belonging to the subfamily bark beetles (Scolytinae). It originates from Africa and is spread around the world due to the trading and transportation route.

<i>Gyrinus natator</i> Species of beetle

<i>Vespula atropilosa</i> Species of wasp

Vespula atropilosa, also known as the prairie yellowjacket, is a black and yellow social wasp that forms annual colonies. Vespula atropilosa was formerly a member of the Vespa family. Males have either xanthic (yellow) or melanic (black) abdominal coloring. The prairie yellowjacket can be found in the Western and Midwestern United States as well as parts of southern Canada. It builds its nests underground and prefers large open areas such as pastures and golf courses. Vespula atropilosa colonies are founded by a queen in the spring and grow most during mid-summer. It preys on other insects such as flies and grasshoppers but is not a scavenger like other wasps. Queens mate with multiple males, and males will fight each other for matings. V. atropilosa is a social wasp that practices altruism. Prairie yellowjackets are not considered pests but are commonly found in backyards in the Pacific Northwest. This species derives its common name from the prairies and grasslands where it can be found.

<i>Ceutorhynchus obstrictus</i> Species of beetle

Ceutorhynchus obstrictus, the cabbage seedpod weevil, is a species of snout beetles or true weevils which is widespread in Europe and lives on several types of crucifers. The adult weevils feed on the leaves, but breed in the seedpods, where the larvae destroy the seeds. It can be a harmful pest on crops like rapeseed/canola, cabbage and relatives or Brassica rapa.

<i>Gyrinus minutus</i> Species of beetle

Gyrinus minutus is a species of whirligig beetle in the family Gyrinidae. It is found in North America and Europe.The body is entirely black with a dull appearance due to its microsculpture. G. minutus typically inhabit open edges of larger water bodies like lakes and reservoirs but also reside in sparsely vegetated ponds and slow-flowing river parts. Their swimming abilities are weaker than other gyrinids, and they often disperse in groups when disturbed. Reproduction begins in early spring with mating on water surfaces, followed by egg-laying on aquatic plants. Larvae hatch after a week, growing quickly and reaching maturity within three to four weeks. They are capable of flight, and adults can be found in new locations throughout the summer. G. minutus lacks volatile production for predator defense or has minimal amounts, likely due to its behavior and habitat preferences. Interestingly, while G. minutus rarely aggregates, it can still respond to alarm signals from other species.
