Eucera amsinckiae

(Timberlake, 1969)

Eucera amsinckiae is a of long-horned in the , first described by Timberlake in 1969. The species belongs to the Eucera, which comprises solitary bees commonly known as squash bees due to their specialized association with plants. Males of Eucera species are characterized by exceptionally long , a trait that gives the group its . Like other members of its genus, E. amsinckiae is likely an important of agricultural crops, particularly those in the Cucurbitaceae family.

Identification

Males can be identified by their extremely long , a diagnostic feature of the Eucera. Females may be confused with other large, such as Anthophora , but can be distinguished by morphological details of the and facial structures. Species-level identification of E. amsinckiae specifically requires examination of genitalic characters and comparison with related Eucera species.

Habitat

typical for the include agricultural areas, gardens, and natural areas where plants of the Cucurbitaceae occur. The likely nests in the ground, as is characteristic of Eucera.

Distribution

The has been recorded from Middle America and North America based on GBIF distribution data. Specific locality details within these regions are limited in available sources.

Seasonality

Activity period likely follows the flowering of plants, with peak activity during summer months when these crops are in bloom. This pattern is consistent with other Eucera .

Diet

feed on nectar from flowers. Based on -level characteristics, are provisioned with pollen, likely from Cucurbitaceae and related plant .

Host Associations

Cucurbitaceae - pollen sourceInferred from -level association; specific plants for this not documented in available sources

Life Cycle

As a solitary , females construct individual nest burrows in the soil. Nests are provisioned with pollen and nectar, on which are laid. develop within the nest , pupate, and emerge as the following season. This pattern is characteristic of the but specific details for E. amsinckiae are not documented.

Behavior

Males are known to patrol nest entrances in search of mates, a common in the . Foraging activity is focused on pollen and nectar collection from plants.

Ecological Role

Likely serves as an important of crops and related wild plants. Eucera are recognized as efficient pollinators due to their specialized association with Cucurbitaceae.

Human Relevance

Contributes to pollination services for squash, pumpkin, and other crops. The value of wild Eucera in agricultural systems has been demonstrated in studies of related .
