Death on a Calla Lily

Mar 30, 2010

It probably wasn't colony collapse disorder.

Probably not pesticides, a disease, malnutrition or stress, either.

It could have been a pest.

When we were walking through the Carolee Shields White Flower Garden at the UC Davis Arboretum last weekend, we spotted the still body of a honey bee on a white calla lily (Zantedeschia aethipica), a native of South Africa. 

It seemed so incongruous. It was spring in the garden. Worker bees at the nearby Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis are bustling out of their hives, collecting nectar and pollen for their expanding colonies.

Worker bees live only four to six weeks during the busy season. But this isn't the busy season.

"What happened to the bee?" someone inquired, after seeing the photo. "How did she die?"

"Don't know," I said. It probably wasn't pesticides, though. The garden is pesticide-free.

Extension apiculturist Eric Mussen, member of the UC Davis Department of Entomology, speculated that a spider hiding inside the blossom may have killed the bee and then sucked its blood.

"Spiders do that--they lurk inside the blossoms," he said.

Another pest of the beleagered honey bee.
