Insects record wood sawfly food.

Sawing bees, also known as leaf-cutting bees, suck nectar like other bees.

Common sawflies are white with stripes. It often lives in earthworm tunnels. If you go to the mud beach and squat down and search carefully, it is not difficult to find such a tunnel. Wood-leaf bees don't regard all tunnels as their homes, because the depths of tunnels are often dark and humid, which is not suitable for discharging waste, and sometimes they are attacked by insects. So it uses the seven or eight inches long place near the ground as its own residence.

Woodleaf bees will meet many natural enemies in their lives. After all, the tunnel is not a safe and solid fortification. Cut off a lot of bits and pieces of small leaves, and the depth is blocked. These small leaves, which are used for plugging, were cut off from the leaves by wood sawworms accidentally. So it looks fragmented, not as neat as those small leaves used to build nests.

There are a bunch of small nests above the fortifications of the sawfly, about five or six. These nests are made of small leaves cut by sawflies. These small leaves used for nesting are much more demanding than those used for fortifications. They must be broken leaves of the same size and neat shape. Round leaves are used for the nest cover, and oval leaves are used for the bottom and edge.

The small leaves of the sawfly are cut with its knife-its mouth. In order to meet the requirements of various parts of the bird's nest, it often uses this pair of scissors to cut out small leaves of different sizes. For the bottom of the nest, it is often carefully designed and unambiguous. If the larger blade can't completely match the cross section of the tunnel, it will make a nest bottom with two or three smaller oval blades until it closely matches the cross section of the tunnel, leaving no gap.

What makes the nest cover is a round leaf. It seems to be precisely planned with compasses, which can cover the nest perfectly and seamlessly.

After making a series of nests, the sawfly began to cut off many leaves of different sizes and rub them into a plug to block the tunnel.
