Macrosiagon limbata was first discovered in 1781 by the famous zoologist Johan Christian Fabricius.

The following instars don't have legs, and feed on larvae or stored pollen and nectar supplies.

[3] Adult Macrosiagon limbata are active in summer and can be found on flowers such as elderberries and goldenrod.

[1] Microsiagon limbatas are often confused with tumbling flower beetles (Mordellidae) but differ in length of elytra.

Sweep-netting on flowers and low vegetation during summer months is the best method for capturing these beetles.
