The timberman beetle (Acanthocinus aedilis) is a species of woodboring beetle belonging to the longhorn beetle family. [1]

It is found in woodlands, with a large distribution through Europe, Russia and Central Asia. It is also known as the Siberian Timberman due to its range extending northwards in to Siberia. [2] In Finnish this species is known as Sarvijaakko, in Dutch as Timmerboktor and in Swedish as Större Timmerman. [3] For more vernacular names see the GBIF profile. [4] Despite a few sources suggesting reports in Central America, no confirmed reports were available at time of editing (May, 2020). The species is also not listed as invasive in North America. [5]

The body length ranges from 12-20mm, with antennae up for 3 times the body length in males, or 1.5 times the body length in females. [2] Their lifespan is up to 3 years which includes the 1–2 years spent in the larval stage. [6]

This species is capable of surviving freezing temperatures below -37 °C in both the adult and larval stages. [7] The adults are active from March to June, during which they are diurnal. [2] The adults overwinter in pupal chambers in leaf litter or under the bark. [8]

In Continental Europe, this species has become a serious pest of commercially-grown timber as the larvae feed under the bark, weakening the trees. [2] Through infesting weakened trees, excavating galleries under the bark, the trees then die. [8] Their development within wood debris in natural forests is beneficial for nutrient cycling in forest ecosystems, but can also facilitate the transfer of pathogenic fungi within woodlands. [9] Scots pine (Pinus sylvestris L.) and Norway Spruce (Picea abies) are key food sources for this beetle species. [1]

The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research.

<span class="mw-page-title-main">Longhorn beetle</span> Family of beetles characterized by long antennae

The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described. Most species are characterized by extremely long antennae, which are often as long as or longer than the beetle's body. In various members of the family, however, the antennae are quite short and such species can be difficult to distinguish from related beetle families such as the Chrysomelidae. The scientific name of this beetle family goes back to a figure from Greek mythology: after an argument with nymphs, the shepherd Cerambus was transformed into a large beetle with horns.

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

Histeridae is a family of beetles commonly known as clown beetles or hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other hister beetles, they must be isolated when collected.

<i>Macrodontia cervicornis</i> Species of beetle

Macrodontia cervicornis, also known as the sabertooth longhorn beetle, is one of the largest beetles, if one allows for the enormous mandibles of the males, from which it derives both of the names in its binomen: Macrodontia means "long tooth", and cervicornis means "deer antler". Measurements of insect length normally exclude legs, jaws, or horns, but if jaws are included, the longest known specimen of M. cervicornis is 17.7 cm; the longest known specimen of Dynastes hercules, a beetle species with enormous horns, is 17.5 cm, and the longest known beetle excluding either jaws or horns is Titanus giganteus, at 16.7 cm.

<i>Oemona hirta</i> Longicorn beetle native to New Zealand

Oemona hirta, the lemon tree borer, also known as the whistling beetle or the singing beetle, is a longhorn beetle endemic to New Zealand. Its larvae are generalist feeders, boring into the wood of a wide variety of trees, native and introduced. When citrus orchards were first established in New Zealand, this beetle started inflicting serious damage, and so gained the name "lemon tree borer". Four species within the genus Oemona have been identified, suggesting that more species could be found. When disturbed by predators or humans, the adult beetle stridulates creating a "rasp" or "squeak" sound by rubbing its thorax and head together against an area of thin ridges. Māori would eat a liquid called "pia manuka", which was produced by manuka trees when its wood was damaged by the larvae. When Captain Cook first arrived in NZ, his naturalists, Banks and Solander, collected a lemon tree borer in their first collection between 1769 and 1771. This oldest collected specimen can be found in the British Museum. A few years after the first collection, the species would be first described by the Danish naturalist Fabricius in 1775.
