Stag beetles are among the UK largest insects and spend most of their lives as larvae in dead wood. Their populations can be supported through simple garden management choices.
Stag beetle welfare is almost entirely determined by the availability of decaying wood habitat. Larvae develop slowly over years in dead wood — removing stumps and logs eliminates this habitat completely. Adults emerging in spring and early summer are vulnerable to cars, cats, and well-intentioned but misguided intervention when people mistake them for dangerous insects. Creating log piles and leaving stumps in gardens directly creates stag beetle habitat at individual property scale, making this one of the most accessible invertebrate welfare actions available to homeowners.
