Bees are hardly the biggest creatures in the world - but New Zealand's native bees are even smaller.
How tiny? Almost so small you can hardly see them.
Rachel Weston is a kiwifruit orchardist based in Tauranga with a passion for bees.
Her first book was Bumblebee, her second Bumblebees Have Stinky Feet and her latest is Kiwi Bees Have Tiny Knees.
It's a beautifully illustrated and photographed book that's full of facts about New Zealand's 28 species of native bees - including that one species likes to sip our sweat on a hot day, and that all female native bees live alone.
Rachel joins Kathryn for more fascinating facts about our little known native bee species.
