Thymelicus sylvestris (Poda, 1761) Species

Last modified: Sept. 14, 2023, 2:49 p.m.

A common species in Belgium, especially in the south of the country. In the north it is more local and in recent times it seems to be lacking from the northwest. Possibly the distribution has been overestimated due to identification errors with the more widespread T. lineola.
