If you have some free time or are looking for an outdoor project with kids, you can take pictures of bumble bees and upload them to this website. Scientists there can help you identify them and tell you if they are rare.

Bumble bees seem to like my anise hyssop, milkweed, and sunflowers especially. I tried to take a photo of one just now but it turns out they don’t always sit still for photos. There is only so much you can do for wildlife in an urban situation, but one thing you can do is plant to help bees and butterflies, then have friendly conversations with family, friends and neighbors when they ask what the heck you are doing in your “overgrown” garden and when your “weeds” make attempts to expand beyond your borders.
