Dominance of Capsicum minutiflorum (Solanaceae) pollen in stingless bee hives: An insight into protein composition and foraging behavior by four Meliponini species of the Bolivian-Tucumano forest Stingless bees (Apidae: Meliponini) primarily feed on nectar and pollen from a wide diversity of flowering plants. By doing so they pollinate these flowers thus contributing to biodiversity and ecosys...

Foraging distances in six species of solitary bees with body lengths of 6 to 15 mm, inferred from individual tagging, suggest 150 m-rule-of-thumb for flower strip distances Bees require suitably close foraging and nesting sites to minimize travel time and energy expenditure for brood provisioning. Knowing foraging distances in persistent (‘healthy’) populations is theref...

Also, it leans on some solitary bee research that we published, namely a study on solitary bee flight ranges available here doi.org/10.3897/jhr....

The secret life of the solitary bee Solitary bees are a diverse group of wild bees that nest alone rather than in hives or colonies like honeybees or bumblebees

Most people don’t realise the ecological value of solitary bees. This nice article explains why they are important to biodiversity and food security.

A colorful graphic promoting World Bee Day. On the left side, a large illustrated bee is centered above two open hands surrounded by various nature and food icons like a leaf, butterfly, bird, onion, pumpkin, passionfruit, watermelon, flowers, and a bat. The background is yellow with honeycomb patterns and black dots. On the right side, the text reads: “20 May World Bee Day” and “BEE INSPIRED by nature to nourish us all” on a light background.

Happy #WorldBeeDay!

On the day to appreciate the critical role of bees and other pollinators in the health of our planet’s ecosystems, we are grateful we are part of the global effort to know and protect these precious buzzers.

A photo showing a close-up lateral view of a small parasitic wasp specimen. The wasp has a slender, dark body with light brown and yellowish legs. Its antennae are long, segmented, and thread-like, extending forward. The wings are translucent with a noticeable iridescent sheen and distinct venation patterns. The head is small with prominent compound eyes.
