Peponapis pruinosa is a species of solitary bee in the tribe Eucerini, the long-horned bees. Its common name is the eastern cucurbit bee. It may be called the squash bee, but this name can also apply to other species in its genus, as well as the other squash bee genus, Xenoglossa . [1] This bee occurs in North America from the East Coast of the United States to the West Coast and into Mexico. It is an oligolege, specializing on a few host plants, the squashes and gourds of genus Cucurbita . Its range expanded as human agriculture spread throughout North America and squash plants became more abundant and widespread. [2] [3] It may also have spread naturally as the range of its favored wild host plant Cucurbita foetidissima expanded. [4]

This bee is 11 to 14 millimeters long and 4 to 5.5 millimeters wide at the abdomen. It is black with whitish bands on the abdomen and it is coated in yellowish hairs. [2] Branched hairs or scopae on the hind legs help to carry the large, coarse pollen of cucurbits. Males lack scopae, as they do not collect pollen. [5]

This bee relies on wild and cultivated squashes, pumpkins, gourds, and related plants. It may occasionally obtain nectar from other types of plants, but the female will only use Cucurbit pollen to provision her young. [6] Females dig a nest in the ground near its host plants. The nests are known to reach depths of 46 centimeters, but the offspring are usually placed at shallower depths. [3] The bee seems to favor irrigated soils and soils cleared by fire. [7] It may also nest in lawns. [8] The bee will sometimes plug the nest just below the surface, and it may place a tumulus at the entrance. [8] Nest building activity often occurs later in the day, as mornings are usually spent foraging. [8] The squash flower opens early in the morning and closes before noon, and the bee's activity pattern is tied to the flower's cycle. [6] The male bee spends most all of his time in and around flowers, foraging and mating in the open flowers and sleeping inside the closed flowers after noon. [2] [8] The females live in and around the flowers until nesting season, when they live in and maintain one or more nests. [2] The young pupate in late June and early July. [9]

This species is an important pollinator of cultivated crops of squash, pumpkins, and related plants. A squash field with a healthy population of squash bees can be completely pollinated with no need for the introduction of honeybees. [6] This ground-nesting bee often spends its entire life in an irrigated crop field, and there it can face a number of hazards, such as tillage and pesticides. [7] The effects of tillage on P. pruinosa are so great that tilled farms may have three times fewer squash bees than a farm with no tillage. [10] The bumblebee Bombus impatiens has also been found to be a good pollinator of squash, pumpkins in particular. [11]

<i>Cucurbita</i> Genus of herbaceous vines in the gourd family, Cucurbitaceae

Cucurbita is a genus of herbaceous fruits in the gourd family, Cucurbitaceae, native to the Andes and Mesoamerica. Five edible species are grown and consumed for their flesh and seeds. They are variously known as squash, pumpkin, or gourd, depending on species, variety, and local parlance. Other kinds of gourd, also called bottle-gourds, are native to Africa and belong to the genus Lagenaria, which is in the same family and subfamily as Cucurbita, but in a different tribe. These other gourds are used as utensils or vessels, and their young fruits are eaten much like those of the Cucurbita species.

<i>Cucurbita pepo</i> Cultvated plant that yields varieties of squash and pumpkin

Cucurbita pepo is a cultivated plant of the genus Cucurbita. It yields varieties of winter squash and pumpkin, but the most widespread varieties belong to the subspecies Cucurbita pepo subsp. pepo, called summer squash.

The zucchini, courgette or baby marrow is a summer squash, a vining herbaceous plant whose fruit are harvested when their immature seeds and epicarp (rind) are still soft and edible. It is closely related, but not identical, to the marrow; its fruit may be called marrow when mature.

<i>Cucurbita ficifolia</i> Plant species cultivated for edible shoots, leaves, flowers, fruit, and seeds

Cucurbita ficifolia is a species of squash, grown for its edible seeds, fruit, and greens. It has common names including Asian pumpkin, black seed squash, chilacayote, cidra, fig-leaf gourd, and Malabar gourd. Compared to other domesticated species in its genus, investigators have noted that samples of C. ficifolia from throughout its range are relatively similar to one other in morphology and genetic composition. Variations do occur in fruit and seed color, some isozymes, and photoperiod sensitivity.

<span class="mw-page-title-main">Squash bee</span> Tribe of bees essential for cucurbit pollination

The name squash bee, also squash and gourd bee, is applied to two related genera of bees in the tribe Eucerini; Peponapis and Xenoglossa. Both genera are oligoleges on the plant genus Cucurbita and closely related plants, although they usually do not visit watermelon, cucumber, and melon plants. They are small genera, containing only 13 and 7 described species, respectively, and their combined range is nearly identical to the range of Cucurbita in the New World, from South America to North America. Their range has become somewhat expanded along with the movement of cucurbits into other areas.

A pumpkin is a vernacular term for mature winter squash of species and varieties in the genus Cucurbita that has culinary and cultural significance but no agreed upon botanical or scientific meaning. The term pumpkin is sometimes used interchangeably with "squash" or "winter squash", and is commonly used for cultivars of Cucurbita argyrosperma, Cucurbita ficifolia, Cucurbita maxima, Cucurbita moschata, and Cucurbita pepo.

<i>Bombus vosnesenskii</i> Species of bee

Bombus vosnesenskii, the yellow-faced bumblebee, is a species of bumblebee native to the west coast of North America, where it is distributed from British Columbia to Baja California. It is the most abundant species of bee in this range, and can be found in both urban and agricultural areas. Additionally, B. vosnesenskii is utilized as an important pollinator in commercial agriculture, especially for greenhouse tomatoes. Though the species is not currently experiencing population decline, urbanization has affected its nesting densities, and early emergence of the B. vosnesenskii has been implicated in the increasing lack of bee diversity on the West coast.

<i>Bombus fervidus</i> Species of bee

Bombus fervidus, the golden northern bumble bee or yellow bumblebee, is a species of bumblebee native to North America. It has a yellow-colored abdomen and thorax. Its range includes the North American continent, excluding much of the southern United States, Alaska, and the northern parts of Canada. It is common in cities and farmland, with populations concentrated in the Northeastern part of the United States. It is similar in color and range to its sibling species, Bombus californicus, though sometimes also confused with the American bumblebee or black and gold bumblebee. It has complex behavioral traits, which includes a coordinated nest defense to ward off predators. B. fervidus is an important pollinator, so recent population decline is a particular concern.

<i>Bombus impatiens</i> Species of insect

Bombus impatiens, the common eastern bumble bee, is the most commonly encountered bumblebee across much of eastern North America. They can be found in the Eastern temperate forest region of the eastern United States, southern Canada, and the eastern Great Plains. Because of their great adaptability, they can live in country, suburbs, and even urban cities. This adaptability makes them a great pollinator species, leading to an increase in their commercial use by the greenhouse industry. This increase consequently led to their farther spread outside their previous distribution range. They are considered one of the most important species of pollinator bees in North America.

<i>Eucera</i> Genus of bees

Eucera is a genus of bees in the family Apidae, which comprises more than 100 species. These bees are commonly known as long-horned bees due to their characteristically long antennae, especially in males. Eucera species can be found in diverse habitats, including meadows, fields, and urban gardens, primarily in the Palearctic and Nearctic regions, covering parts of Europe, Asia, North Africa, and North America.

<i>Ptilothrix</i> Genus of bees

Ptilothrix is a genus within the tribe Emphorini of the family Apidae. Bees of this genus can range from 7 to 15 mm. Ptilothrix species are solitary, ground-nesting bees.

<i>Bombus vancouverensis</i> Species of bee

Bombus vancouverensis is a common species of eusocial bumblebee of the subgenus Pyrobombus. B. vancouverensis inhabits mountainous regions of western North America, where it has long been considered as a synonym of Bombus bifarius, and essentially all of the literature on bifarius refers instead to vancouverensis. B. vancouverensis has been identified as one of the two species of bumblebee observed to use pheromones in kin recognition. The other is the frigid bumblebee, Bombus frigidus.

Bombus hypocrita, also known as the short-tongued bumblebee, is a Japanese bumblebee commonly used in commercial pollination. These short-tongued bumblebees have a proboscis about 7-9mm long, which is folded under their head when flying. Bumblebees are a small fuzzy insect with yellow and black banding along their abdomen. They are round and covered in pile, the hair-like structures that give them their distinct fuzzy appearance.
