Re sending this photo of a dead western honey bee very like the live one i sent you six weeks ago- in the same spot in our back yard. At the same time now there are dozens of dead non-native bees steps away by our garage door. Last fall we had a mountain of dead ones, same place. Any idea as to what’s causing this bee- kill? We thought it was heat last year but these past few days besides the smoke- smog from valley fire it’s been cool and damp here. More dead bees today.
