The Cylindropuntia cactus at the 30th St Greenhouse is a real magnet for Lithurgopsis apicalis, a cactus specialist! Notice the tubercles (tiny horns) on top of her head! There were dozens of females visiting flowers and foraging for pollen. I had seen these on Opuntia while out on the plains, but the Cylindropuntia is from the southwest. Apparently, our Opuntia specialist likes it too!
The things we do for love. The checkerspots were in need of some sunlight so I had to carry them outside since the greenhouse is currently being renovated. Luckily a little honey water to set the mood, some fresh air, and a couple hours of daylight is all it takes to ensure we get some happy couples!
