ALT A ball of small tan rocks glued together, 5 feet up in a white-thorn acacia (old name). It’s a bee nest! The bee is in the genus Dianthidium, known as pebble bees. I had never heard of them until last night as I looked through my set of Native Bees of the Western United States cards that Krystle Hickman put together (a kickstarter project) that I received yesterday.

ALT One of the cards in the Native Bees of the Western United States volume 1 set by Krystle Hickman. On the left side is a photo of a small black and yellow bee on a yellow flower. On the right side is a photo of the round pebble nest that the females make on a branch (some are on the ground). There is more information on the other side of the card. I had an Aha! moment when I saw one of the pebble nests for the first time today. I remembered seeing the card as I looked through the set, so I was able to partially identify the nest on iNaturalist. I’d have to see the bee to maybe identify it to species.
