Melissodes dentiventris is a non-woven insect from the family of bees and bumblebees (Apidae). The scientific name of the species was first validly published in 1854 by Smith.

The eastern cucurbit bee (Peponapis pruinosa) is a picky eater who sticks with their preferred host plants, which include squash. Males are known to spend most of their time around flowers, even sleeping in them during the night. While it isn't known to be harmful, it still ends up being caught in pesticides intended for other insects.

Xeromelecta californica is a non-woven insect from the family of bees and bumblebees (Apidae). The scientific name of the species was first validly published in 1878 by Cresson.

The vibrant, metallic sheen of dilemma Orchid Bee glistens in hues of green, and blue as it diligently pollinates a variety of tropical flowers. Known for the males' remarkable ability to collect and store flower scents in specialized hind-leg pouches, these creatures play a crucial role in the ecosystems they frequent, aiding in the successful reproduction of numerous plant species. With their impressive fragrance collection, males create complex olfactory signals to attract mates, demonstrating a sophisticated interplay between flora and fauna.

Eulaema cingulata is a fleece-winged insect from the family of bees and bumblebees (Apidae). The scientific name of the species was first validly published in 1804 by Fabricius.

The head of Eulaema mocsaryi has a central raised ridge and both head and thorax are clad in short velvety black hairs. The colour of head and thorax is mainly black. The legs are black and hairy and the tibial joints of the hind legs are wide and compressed. The dark-coloured abdomen is densely covered with short tawny-yellowish hairs, becoming paler towards the tip of the abdomen.

Eulaema meriana resembles a bumblebee in appearance and is covered in short dense hairs. At first glance Eulaema bees look like large bumblebee queens. They are relatively large bees with faint metallic colorations. The head of the bee is black, and the thorax brownish black with a large, glossy black scutellum. Their abdomen is black with three transverse pale yellowish bands on the anterior half, and the posterior third is reddish brown. E. meriana also possess membranous wings that are dark at the base and paler at the tips. The legs are black and the tibia of the hind legs are much thicker. Males possess hollows on their hind legs, while females have pollen baskets. In general, the species have long tongues that are thought to be an evolutionary adaptation that favors nectar collection. The large body size is thought to allow the bees to fly in cooler, rainy conditions and continue foraging. It has also been suggested that the larger body size can help them forage for longer distances.
