Beetle

  • What ladybugs really are
    Ladybugs are more than cute red beetles with spots. They are chemically defended lady beetles, many of them voracious predators of aphids and other pests, and some—like the multicolored Asian lady beetle—have become invasive indoor nuisances with real ecological impacts.

    Tiger beetles are some of the most charismatic insects on Earth: metallic, sharp-eyed, absurdly fast, and every bit as predatory as their name suggests. Come learn how they hunt, why their larvae live like tiny trapdoor monsters in the soil, and what their decline says about the fragile open habitats many other species need too.

  • Tyloderma variegatum

    hidden snout weevil

    Tyloderma variegatum is a species of hidden snout weevil in the beetle family Curculionidae. It belongs to the genus Tyloderma, a group of weevils characterized by their concealed snout morphology. The species epithet 'variegatum' suggests variable or mottled coloration, though specific pattern details are not well documented. Very few observations of this species have been recorded.

  • Uleiota

    Uleiota is a genus of beetles in the family Silvanidae, first described by Latreille in 1797. The genus contains approximately 35 described species distributed across multiple continents. Members of this genus are classified within the subfamily Brontinae and tribe Brontini. The genus has been recorded from Europe, North America, South America, Africa, Asia, and Australia, indicating a broad geographic distribution.

  • Vacusus vicinus

    Common Anthicid

    Vacusus vicinus is a species of antlike flower beetle in the family Anthicidae. It has a broad geographic distribution spanning the Caribbean, Central America, North America, Oceania, and South America. The species is commonly encountered, with over 600 observations documented on iNaturalist.

  • Xanthochroa lateralis

    Xanthochroa lateralis is a species of false blister beetle in the family Oedemeridae. The species is known from North America. Oedemeridae beetles are commonly referred to as false blister beetles due to their resemblance to true blister beetles (family Meloidae), though they lack the cantharidin toxin that gives blister beetles their common name.

  • Xanthocomus

    Xanthocomus is a genus of small beetles in the family Phalacridae, order Coleoptera. Members of this genus are part of a family commonly known as shining flower beetles or oval beetles. The genus is poorly documented in scientific literature, with limited available information on its species diversity and biology.

  • Xarifa

    Xarifa is a genus of beetles in the family Ptinidae, order Coleoptera. Members of this genus are small to minute beetles commonly known as spider beetles. The genus name is also shared with a 19th-century sailing yacht that served in the U.S. Navy during World War I, but this naval vessel is taxonomically unrelated.

  • Xyletinus fucatus

    Xyletinus fucatus is a small beetle species in the family Ptinidae (formerly Anobiidae), described by John Lawrence LeConte in 1865. The species is recorded from multiple Canadian provinces including British Columbia, Manitoba, and New Brunswick, indicating a transcontinental distribution across northern North America. As a member of the subfamily Xyletininae, it belongs to a group commonly known as deathwatch beetles or furniture beetles, though specific ecological details for this species remain poorly documented.

  • Xyletinus pubescens

    Xyletinus pubescens is a species of beetle in the family Ptinidae (formerly treated as Anobiidae). It was described by LeConte in 1878 and is known to occur in North America. The genus Xyletinus contains wood-boring beetles, though specific details about this species' biology remain poorly documented.

  • Xylotrechus nitidus

    Xylotrechus nitidus is a species of longhorned beetle in the family Cerambycidae, first described by George Henry Horn in 1860. It belongs to the tribe Clytini, a group commonly known as the "round-necked longhorns." The species epithet "nitidus" (Latin for "shining" or "polished") likely refers to the beetle's glossy appearance. This species is part of a large and diverse genus containing over 200 species worldwide, many of which are wood-boring beetles associated with various hardwood trees.

  • Zeadolopus

    Zeadolopus is a genus of small carrion beetles in the family Leiodidae, endemic to New Zealand. The genus was established by Thomas Broun in 1903 and comprises several species of round fungus beetles. Members of this genus are part of the tribe Leiodini within the subfamily Leiodinae. The genus is poorly studied, with limited published information on species-level diversity and natural history.

  • Zeugophora varians

    Zeugophora varians is a species of megalopodid leaf beetle in the family Megalopodidae. It was described by Crotch in 1873. The species is found in North America, with records from Canada including Alberta and British Columbia. Megalopodid beetles are a relatively small family of leaf-feeding beetles closely related to Chrysomelidae.
