Today’s featured insect is a leaf beetle (family Chrysomelidae) from the genus Calligrapha, which includes over 100 species. Found throughout North and Central America, these beetles are notable for the intricate, high-contrast “ink spot” markings on their wing covers (elytra).

Today’s featured insect is the eastern poplar buprestid (Poecilonota cyanipes), a metallic wood-boring beetle native to North America. Found from subarctic Canada to the southern U.S., its larvae tunnel beneath the bark of weakened poplar, aspen, and willow trees.

Today’s featured insect is Gyrinus wallisi, a whirligig beetle (family Gyrinidae) from Churchill, Manitoba. These carnivorous aquatic beetles swim in circles on the water of lakes and ponds, using split eyes to see above and below the surface at once!

Today's featured insect is Huddlestonium exu, a rare parasitic wasp from Kruger National Park, South Africa. It is the sole species in its genus and belongs to the tiny family Geoscelionidae, which has only eight species — most known from ancient amber millions of years old.

Today's featured insect specimen is the convergent lady beetle (Hippodamia convergens), whose range includes much of North America. Both adults and larvae are predators of aphids. Females can lay over 1,000 eggs over the course of spring and summer.

Today's featured insect specimen from Nunavut is the fiery scavenger beetle, Corticaria ferruginea (family Latridiidae). These minute brown scavenger beetles, along with their larvae, feed exclusively on the hyphae and spores of fungi, moulds, and mildews.

Today's featured specimen is the giant mayfly, Hexagenia limbata. It's the most widely distributed mayfly in North America. Its aquatic larvae live in mud burrows in lakes and rivers. Adults have vestigial mouthparts, do not feed, and live only long enough to reproduce.

Today's featured insect from Ecuador is a specimen of Titanacris, a small genus of just seven arboreal species of tropical South American grasshoppers. They are renowned for their large size and strikingly coloured hindwings, which are flashed to startle predators.

Today's featured insect from Australia is the striped sun fly (Tapeigaster nigricornis). Closely associated with fungi, this striking heleomyzid fly is often encountered on or near mushrooms. Adults spend much of their time basking in sunny woodland patches.

Today's featured insect is Leiodes longitarsis, the long-footed round fungus beetle, from Churchill, Manitoba. Described in 1993, this small round beetle feeds on fungi, slime molds, and other molds growing on decaying organic matter and forest debris.

Today's featured insect is Pseudomyrmex gracilis, the slender twig ant. Found from the southern USA to Argentina and Brazil, it nests in hollow twigs and small branches. It delivers a painful sting and aggressively defends its host plant by swarming and stinging intruders.

Today's featured insect is the ornate checkered beetle, Trichodes ornatus (Family Cleridae), from the Yukon. Females lay eggs on flowers and the larvae hitch rides on solitary bees back to their nests where they feed on bee larvae. Adults also prey on bees visiting flowers.

Today's featured insect is Palmia praecedens, a rare clearwing moth (Family Sesiidae) known from only a handful of verified records since its description in 1883. It is associated with oak woodlands in southern Arizona's mountains, with additional records from North Carolina.

Today we feature a Rust Fly (Family Psilidae) from the Serengeti National Park, Tanzania. Their larvae (maggots) typically burrow into the roots and stems of plants where they feed and develop. Some species are significant pests of root crops such as carrots and parsnips.

Today we feature a pseudoscorpion. These arachnids have venomous scorpion-like pincers but no tail or stinger. Many pseudoscorpions practice phoresy — hitchhiking on larger animals such as beetles, flies, birds, and small mammals to reach new habitats without harming their hosts.

Today’s featured insect specimen from Manitoba is Arhopalus foveicollis, the Pitted Longhorn Beetle (Cerambycidae), described in 1847. Its larvae develop in dead or dying conifers like pine and spruce in boreal forests after wildfires, where they’re usually found in tree stumps.

Today’s featured insect is a Neriid fly (genus Glyphidops) which typically breed in rotting vegetation. Males are highly territorial and are known for dramatic displays and intense fights over access to females, often using their elongated bodies and legs to intimidate rivals.
