Mr. and Mrs. Digger Dining Together

Digger bees are devoted sunflower seed setters, as they love the sunflower family blooms.  I was very lucky to capture both male and female digger bees dining side by side.  Learn a bit more about digger bees here.IMG_6934

Lady digger is on the left and mister digger is on the right.  The male has very long antennae for mating purposes.  Check out the video posted on YouTube by Karla Thompson.

Please do share what you learn, and thank you for joining the movement to save our bees!

Leafcuttter Bee (Megachile) in Action

Yesterday was one of my lucky days, as I was able to capture leaf cutter bees cutting their half-moon shaped pieces out of my raspberry bushes, not just once, but three times!  I think you should see what this looks like up close too!  If you’d like a quick refresher, or you’d like to learn about the leaf cutter bee, follow this LINK.

Melissodes: Longhorned, Digger Bees

Digging for the future…

IMG_4336

I introduce to you, the Melissodes bee! Look at the pollen all over this bee, and check out those antennae! Commonly named the Long horned digger bees, these beauties are late to emerge, and pollinated flowers of similar timing, such as gumweed seen in this photo.  I spotted these bees on a hike up Mt. Sanitas in Boulder, CO, last week (August), and of course had to pull out the camera!

The bee in the picture is a male, and I know this because he has very long antennae, whereas the females have shorter antennae, about half the length of the male’s.  Unfortunately, I didn’t see any females the day of the Mt. Saints hike.  This is likely due to the fact that males emerge sooner than females, and I was lucky enough to witness the beginning of digger bee season!

However, I may have seen a female on a hike last fall near Frisco, CO.  Have a look. What do you think?

Another difference between the sexes of these bees, is where they slumber.  Males will cluster together on plants, or in crevices in rocks stacked on top of each other to keep warm until morning.  Females sleep underground in the nest they are building.

The title “digger bee” has a literal meaning here.  The females dig into the ground to create nesting cavities.  They like loose sandy soil, because they will backfill the nesting hole with loose sand every time they leave to forage for nectar and pollen.  This serves to camouflage the nest, thus protecting it from predators.  Although these bees are solitary, they will happily form aggregations of neighboring nests, and sometimes even sharing an entrance leading to many different nesting rows of different lady bees!

Longhorned bees are late arrivals, and have been known to fly into October, pollinating fall blooms. They gravitate toward flowers in the sunflower family, but they’ll happily behave as a generalist and take whatever nectar and pollen is available at the time.

Look at this photo bomber bee! I was photographing the butterfly, and didn’t realize I had captured two pollinators!  Can you identify this bee now?

If you’d like to see these bees nest in your yard:

  1. Grow lots of sunflowers and late blooming perennials.
  2. Provide a small mound of sandy soil.
  3. Take the time to observe everyday, because the smallest creatures are also the hardest to catch in the act of living!

Cheers to joining this very important movement!

 

 

Moth to Yucca to People

This week I have the opportunity to teach children about the benefits pollinators presented to the Pueblo People, and I know you will enjoy this topic just as much, so here it goes!

YUCCA POLLINATION

Yucca plants rely on yucca moths to pollinate them, and yucca moths rely on yucca to feed their young.

Obligate mutualism is the name of the game with the yucca: yucca moth relationship.  One cannot survive without the other.

Yucca blooms open early summer, inviting visitors with sweet nectar and shelter within its petals.

Yucca blooms release the most concentrated scent at night, and produce the most nectar in the evening hours, and reason for this, is their most important pollinator flies at night.

Yucca moths fly at night, making them nocturnal. They search for a yucca bloom to take refuge in, and scent plays a large role in moths finding the blooms.  Inside the yucca bloom, the yucca moths will mate.

Once mated, the female yucca moth will collect pollen from the anthers on the yucca bloom, and store it under her chin.

She will then fly to another yucca bloom, lay a few eggs, and deposit some pollen from under her chin onto the stigma of the bloom where her eggs will hatch.  She knows this will result in seeds.

The larvae of the yucca moths feed on the seeds of yucca plants.  The mother moth knows to lay only a few eggs in each bloom, so the bloom doesn’t abort and fail to feed her young.

In many cases, pollinators do not know they are pollinating flowers to form seeds, but this clever girl is very much aware of her purpose for the yucca plant.  Her efforts benefit more than just her young. 

YUCCA AND THE PUEBLO PEOPLE

The Pueblo people used the yucca plant from top to bottom!

The blooms are sweet, and can be eaten straight off the plant.  Those blooms will also become a tasty fruit that can be eaten alone or paired with other foods.

The leaves are tough and fibrous, and can be shredded down to pieces perfect for weaving baskets, sandals, and blankets.

The tips of those fibrous leaves are sharp, and can be used as needles for sewing.

The roots of yucca plants make excellent soap and shampoo when ground into a pulp and mixed with a little water.  The roots can also be used as a remedy for rashes and sores.  They can be eaten, but have a soapy flavor.

This pollinator isn’t a bee, but very important nevertheless! What a plant, and what a moth!

Mason Bee Larva!

Check out this video to spy some live mason bee larva.

Below is a picture of the inside of my observation native bee house.  You are looking at two males nestled in the top rows resting, and three individual egg cells filled with pollen and nectar, and separated by mud in the bottom rows.  This is before the eggs hatched into larva, and the video I took tonight shows the larva, which are growing more chubby every day.  The next phase will be the larva spinning a cocoon around themselves to develop into pupa and then adults, which will emerge next March.  This is so cool watching the entire process!
