I released some ladybugs a while back and they seem to be happlily reproducing in my garden.
Bumblebees love the Valerian flowers. These flowers have reseeded throughout the garden and give off a pleasant heliotrope-like fragrance. This little guy has a tattered wing.
I got this "summer mason bee" house this spring. Some solitary bees like small holes and are active during the summer. A bee is using it! I haven't seen who filled them, but I'm watching and I hope to get more photos of the visitor.
I have Orchard mason bee houses that get used each spring. They have a larger hole than these.
