Michal planted a Redbud from our Free Tree Giveaway last year, and it’s doing beautifully in his yard. But recently, some nibbles at the leaves had him concerned about the health of the tree. He looked around for caterpillars, but none seemed to be hanging about.

After a little digging, it looks like this type of hole is indicative of Leaf Cutter Bees, and one of their favourite go-to snacks is the Redbud leaf. These gentle native bees are solitary and do not have a hive to defend, and are therefore not interested in stinging you. Instead they nest in holes; you can help them out by leaving your garden a little messy in the autumn with hollow stems, or by putting up a bee box to invite these fantastic pollinators into your yard.
