What is the necessary larval food source intrinsically linked to the distribution of US stag beetles?
Answer
Decaying wood, specifically the stumps and root systems of dead hardwood trees
The distribution of stag beetles is fundamentally dependent upon the availability of their specific larval food source, which necessitates decaying wood. More precisely, the larvae, or grubs, require the decaying stumps and root systems of dead hardwood trees such as oak, maple, or hickory. This dependence acts as a powerful limiting factor for their presence; regions lacking this specific type of decomposing organic material, such as arid areas or places dominated by non-hardwood species, offer far fewer acceptable breeding grounds. The larvae spend multiple years consuming this material underground or within the rotting timber to fuel their development.
