Giant resin bee

Giant resin bee

Megachile sculpturalis

A species of Leafcutter bees, Also known as Giant Asian resin bee

The giant resin bee (Megachile sculpturalis) is a big fan of using the environment to their advantage, as they do not bore through wood. Instead, they use pre-existing holes and cap those holes with resin, which is where they earn their name. It is also much larger than other leafcutting bees (Megachilidae), which is where they get the "giant" part of their name.

How and Where Can You Find Giant resin bee at Different Life Stages
Larva Giant resin bee larvae reside in nesting cells created by adult giant resin bee. To find them, seek out nesting sites which may be in hollow stems, wood holes, or other cylindrical cavities. Handle the nesting material with care to avoid disturbance.
Pupal Giant resin bee pupae develop within their nesting cells where the larval stage took place. Locating the pupae involves identifying sealed nesting cells, which can often be found in man-made bee hotels or naturally occurring crevices. Avoid opening the cells, as this can harm the developing giant resin bee.
Adult Giant resin bee adults can be found by observing flowering plants, particularly those that are native to the region and known to attract bees. They may also be attracted to bee hotels. Approach with caution and minimize any disturbance to the foraging giant resin bee.
