Xenoglossa kansensis
Cockerell, 1905
Kansas squash bee
Xenoglossa kansensis, commonly known as the Kansas squash bee, is a solitary long-horned bee in the Apidae. It belongs to a of that are oligoleges on cucurbits (the squash family, Cucurbitaceae). The is native to North America and is one of two related genera (Xenoglossa and Peponapis) commonly referred to as squash bees. Like other squash bees, it is an early-morning pollinator of cucurbit crops.

Identification
Xenoglossa are distinguished from the related Peponapis by subtle morphological features, including differences in male genitalia and facial markings. Males of Xenoglossa typically lack the distinct yellow facial spot characteristic of Peponapis pruinosa males. Both genera share the golden-brown coloration with fuzzy yellow typical of squash bees. Definitive identification to species level within Xenoglossa requires examination of detailed morphological characters.
Habitat
Associated with agricultural and natural where cucurbit plants (Cucurbitaceae) occur, including fields, gardens, and edges of disturbed areas where squash, pumpkin, gourd, cucumber, or zucchini are cultivated or grow wild.
Distribution
North America. Specific range details beyond continental distribution are not well documented in available sources.
Seasonality
Active during the flowering period of cucurbit plants. are early risers, beginning pollination activity before sunrise when squash blossoms open; blossoms typically close around noon, limiting the daily activity window.
Diet
Oligolectic pollen on Cucurbitaceae (squash ). feed on nectar and collect pollen exclusively from cucurbit flowers, including pumpkins, squash, gourds, cucumbers, and zucchini.
Life Cycle
Females are ground-nesters, excavating nests in soil. Males sleep in squash blossoms overnight, awaiting females. Developmental stages include , larva, pupa, and , with larvae provisioned with cucurbit pollen.
Behavior
Solitary with highly specialized foraging . Begins pollinating cucurbit blossoms immediately upon opening in early morning, before other bee become active. Male mating strategy involves overnighting in flowers to encounter females. Non-aggressive; does not defend nests.
Ecological Role
Important native of cucurbit crops and wild Cucurbitaceae. As an oligolectic , it has coevolved with cucurbits and provides efficient pollination services for crop production, including pumpkins and squash.
Human Relevance
Significant agricultural for cucurbit crops. Pollination services support production of pumpkins, squash, cucumbers, and related vegetables. Native to North America, it provided pollination services for of cucurbits prior to European introduction of honey bees.
Similar Taxa
- Peponapis pruinosaAlso a squash bee on Cucurbitaceae; distinguished by male facial markings (yellow spot in Peponapis, absent in Xenoglossa) and subtle genitalic differences
- Apis melliferaNon-native that visits cucurbit flowers later in the day; lacks the early-morning specialization and oligolectic of Xenoglossa

Taxonomic note
Xenoglossa and Peponapis are the two commonly called 'squash bees.' Both are oligoleges on Cucurbitaceae and share similar ecological roles. Xenoglossa kansensis is one of multiple in the genus, though species-level and distributions require further study.
