New research on the habitat requirements of oak longhorn and jewel beetles has just been published. Stephan Vodka and colleagues in the Czech Republic reared beetles from standardised oak-timber baits. The baits were placed in five semi-natural situations: i) old solitary trees in meadows, and, in four situations in forests, ii) abuot 20m high in the crowns or under dense foliage or iii) in full sun or iv) in shady understorey or v) at sunlit edges.
