Kathy Wins Award for Most Bee Monitoring Sessions

Thank you to everyone who joined us at the Volunteer Appreciation Dinner. We had a great time sharing stories and talking about all the accomplishments from this summer.

Kathy was awarded a certificate for completing the most bee monitoring sessions this summer! She volunteered 12 times! That is about 24 hours of bee monitoring time. Congratulations, Kathy! We appreciate all your time and hard work!

Bee of the Week -  Hylaeus bees

Family - Colletidae

Scientific Name- Hylaeus spp .

Hylaeus spp. are known as yellow-faced bees because of the yellow marks on their face and legs. There are 700 species of Hylaeus in the world, and 16 of those species are found in Colorado.

Hylaeus spp. are unique because they don't have any pollen-collecting hairs like most bees. At first glance, they almost look like wasps. Unlike other bees, the females feed on pollen and nectar and then regurgitate it at the nest site for the future young. They are solitary bees nesting in holes already created by other insects or inside twigs. Most of the species are found in forest ecosystems but are also found in urban areas.

Besides the rusty patched bumble bee, the only other bees listed on the endangered species list are seven species of Hylaeus only found in Hawaii. They were listed under the Endangered Species Act in 2016. Hawaii has over 60 Hylaeus species, but these seven species have small habitat ranges. With habitat loss, climate change, and a small habitat range, researchers believe other Hylaeus species have already gone extinct.

Plant of the Week - Baby Blue rabbitbrush

Scientific name: Chrysothamnus (Ericameria) nauseosus var. nauseosus

Rabbitbrush ( Chrysothamnus spp.) can easily be spotted this time of year and is a favorite of bees and butterflies since it provides food late in the season. A native Colorado plant, rabbitbrush has beautiful fall flowers that can continue blooming through November. This dwarf form of rabbitbrush is commonly found along the Front Range. It is a dense plant with silvery-blue leaves and bright yellow flowers. Rabbitbrush is drought, wind, and cold tolerant. If you plant Baby Blue rabbitbrush in your garden, it is recommended that you water it the first year until the plant is established. Do not water the plant after that.

What's the Buzz? Pollinators in the News

"A challenge with lack of knowledge about bees is you can't protect what you're now aware of," says Joseph Wilson, Utah State University. "We could be losing species or causing decline and not even know it."

No Flowers? No Problem. UF Study Shows Bees Have Other Ways of Finding Sugar. This research study shows that native bees can feed on honeydew, a sugary nectar produced by plant-feeding insects.
