The overwhelming majority of research on wild bumble bees has focused on the social colony stage. Nest-founding queens in the early season are difficult to study because incipient nests are challenging to find in the wild, and the foundress queen's flight period is very short relative to the entire

Body size is arguably one of the most important traits influencing the physiology and ecology of animals. Shifts in animal body size have been observed in response to climate change, including in bumble bees (Bombus spp.). Bumble bee size shifts have occurred concurrently with the precipitous popula

Previous studies on bumblebee foraging behavior found that bumblebees often exhibit optimal foraging behavior when collecting nectar and pollen. A popular theory is that bumblebee foraging can be represented by the marginal value theorem (MVT). This summer, I observed the foraging behavior of Bombus

This paper will focus on Syrphidae, an understudied but potentially impactful pollinator. Specifically, I will investigate how the density of the pile (hair) affects the amount of pollen grains carried. This research has the potential to significantly contribute to the field of entomology, as it add

Ethanol is a natural byproduct of yeast fermentation of plant sugars. In flowering plants, yeasts often form mutualistic relationships by inhabiting nectar, where they benefit from access to sugar and confer antimicrobial protection through the production of ethanol. Ethanol in nectar not only shape

Aquatic insects play many critical ecological roles in their environments. Anthropogenic changes in these environments, particularly those already under stress, leave the insect community more prone to stochastic disturbances. Despite widespread efforts by conservationists, many projects fail to inc

Wild bees play indispensable ecological roles in many ecosystems, yet declines in many species have been documented in recent years. These declines have been linked to numerous anthropogenic pressures, including climate change, which can influence bee populations directly (i.e., via physiological me

Abstract Where climate is seasonal, such as in high‐altitude ecosystems, the occurrence and activity patterns of insect pollinators may vary with the varying occurrence of floral resources. This high turnover of species occurrence and interactions may lead to changes in the structure and properties

Organisms inhabiting seasonal environments must fit their life cycle into a limited time window while also synchronizing periods of resource consumption with timing of resource availability. Introduced non‐native species, which often differ in phenology from natives, can alter and expand the seasona

Una polilla minadora de Yucca baccata, Prodoxus phylloryctus (Wagner y Powell), fue documentada por primera vez en el condado Mesa, Colorado. Prodoxus phylloryctus recientemente recibió el nombre común de minador de hojas de Yucca baccata por parte de la Sociedad Entomológica de América. La primera

Animal pollination services are vital for plant reproduction, with approximately 90% of plant species benefitting from this mutualistic relationship. Nectar is one of the most common floral rewards offered by plants in exchange for pollination services. Similarly, nectar is vital for bumbles as they

The role of plant-pollinator interactions is essential for successful plant and pollinator reproduction, thus influencing community assembly of both plants and animals within an ecosystem. Pollinators exhibit competitive behavior in order to collect adequate quantities of pollen and nectar, and bees

Bumble bees are important pollinators in both the wild and in agriculture; however, several species globally are under threat due to multiple anthropogenic factors. One of these threats is climate change, and many bumble bee species have adapted by moving up in elevation. This has only been observed
