Blue Orchard Bee

A metallic dark blue solitary bee that nests in pre-existing holes in wood. It is an exceptionally efficient pollinator of fruit trees, significantly outperforming honey bees per individual.

💡

Did You Know?

A single blue orchard bee can pollinate as effectively as 60 to 80 honey bees, making them increasingly important for commercial fruit production.

Ichneumon Wasp

A large parasitoid wasp with an extremely long, thread-like ovipositor that can exceed the length of its body. Females drill through solid wood to reach their host larvae deep inside.

💡

Did You Know?

The female can somehow detect horntail larvae vibrations through several centimeters of solid wood and then drill her flexible ovipositor to reach them with remarkable accuracy.
