Seeing this leafcutter bee absolutely made my day.
Leafcutter bees are solitary and use these leaf circles to build their nests. The leaves are formed into small cups, into each of which pollen/nectar and an egg are deposited, and then another leaf section is used to seal up the cell.
Rare images of a leafcutter bee sharing its nest with a wolfspider:
These photographs were taken in Queensland, Australia, by an amateur photographer named Laurence Sanders.
The leafcutter bee (Megachile macularis) can be seen fetching freshly-cut leaves, which she uses to line the inner walls of her nest. The wolfspider moves aside, allowing the bee to enter the nest, and then simply watches as the leaf is positioned along the inner wall.
After inspecting the nest together, they return to their resting positions -- sitting side-by-side in the entryway to the nest.
The bee seems completely at ease in the presence of the wolfspider, which is normally a voracious predator, and the spider seems equally unfazed by the fact that it shares its burrow with an enormous bee.
This arrangement is completely unheard of, and the images are a fascinating sight to behold.

Calendula officinalis (pot marigold) and Megachilidae (leafcutter bee)
Pot marigolds are originally from Southern Europe and they've been cultivated for thousands of years, not only as a pretty flower but also as a medicinal herb. Marigolds were used extensively in ancient Roman, Greek, Middle Eastern and Indian cuisines and extracts were also used in dyes and cosmetics. The 'pot' in pot marigold refers to a cooking pot.
Leafcutter bees can be a little hard to identify from the top but if they stick their abdomen up in the air (photo 4) you can see the specialized hairs called scopa which they use to store pollen. If these bees start chewing holes in you garden plants, insecticides won't do any good. Leafcutter bees don't eat leaves - they use them as building material for their ground nests. Like any self-respecting bee, leafcutter bees go straight for the nectar and pollen, and show absolutely zero interest in the salad menu.
LOOK at the leafcutter bee cutting a flower she’s so wonderful and skilled and also she did land on my shirt before doing this what a wonderful little animal
