Sharp; in the stag-beetle larva a series of short tubercles on the hind-leg is drawn across the serrate edge of a plate on the haunch of the intermediate legs, while in the Passalid grub the modified tip of the hind-leg acts as a scraper, being so shortened that it is useless for locomotion, but highly specialized for producing sound.
The lady-bird weighs 150 times less than the stag-beetle, and possesses 5 times more of surface, &c. It is the same with the birds.
Colin would also like to hear from volunteers interested in helping survey stag beetle activity in their own patch.
The stag beetle is listed on Annex II of the EC Habitats Directive.
The rare stag beetle is reliant upon standing deadwood, this tends to rot from the inside to the outside.
