The Midday Sunflower Long-Horned Bee Huddle

The life of the bee as we often think of it is one of constant motion: buzzing, dancing, collecting, feeding, searching, and digging is all in a days work for the “busy bee.”  What many may not realize is that this perception of the bee is mainly from our frequent encounters with the females of the species which must not only feed themselves but also take care of their young.  Honeybees, which are highly unusual in their behavior compared to most bees, have workers that are specialized in gathering pollen and communicating its location through dance, building and cleaning the waxy hive, and taking care of their larval sisters. The vast majority of bee species, unlike the honeybee, are solitary: One female alone must take care of her young; there is no queen or workers to do all the grunt work.

Purple Pollen Eaters: A Honey bee's Love Affair with Phacelia

Spring is here and everyone is totally digging the wildflower display in our Nature Gardens. Casey Schreiner from Modern Hiker even gave us a shoutout on Instagram

It's a good day for #wildflowers at the @nhmla!

The two flowers vying for your attention in this photo are, according to Carol Bornstein Nature Gardens Director and native plant guru, "the white-tipped yellow blossoms of tidy tips, Layia platyglossa, and tansy leaf phacelia, Phacelia tanacetifolia." Carol goes on to explain, "the nectar-rich, sweetly scented purple flowers of this taller annual are attracting droves of bees."  Boy is this true.

Blooming Agaves

More plant news from the North Campus. Recently some of our blue lotus agaves, Agave ceslii 'Nova', have begun to bloom. This is an impressive sight as these plants send forth long spikes, (between four and six feet long), that look a lot like giant asparagus stalks. This type of agave is monocarpic, meaning that it only flowers once, and this particular selection happens to flower at a relatively young age compared to other species. Incidentally, the genus is commonly called century plant because it can take decades for them to flower. The entire stand of this agave (approximately eight plants) is flowering at the same time, because they were all propagated from the same tissue culture, which is a common nursery practice for certain landscape plants. Although flowering signals the end of the plant's lifespan, we can expect to enjoy the flowers and fruits for the next several months!
