Stag Beetles And Wood Boring Insects

    

Stag BeetleThis weekend the wood shed and the discovery of its unique ecosystem kept me busy. To make room for an impending delivery of logs to feed the wood burner throughout the winter, space needed to be created. When I first moved into the house six years ago the wood shed was full to the top with logs, but the resource had been depleted over the years.

Over the summer months the wood shed had become a depository for large items which should have been taken to the tip. Beneath a broken bicycle, deflated football, discarded garden furniture and a bald christmas tree lay a dozen logs lying on a heap of sawdust. I picked up a log and it disintegrated into my hands, a victim of wet rot fungi. Further probing inside the log with a stick revealed a long deceased beetle carcass with huge jaw-like mandibles similar to a stag’s antlers, a distinct feature of the stag beetle.

Debris from decades of wood boring activityStag beetles are harmless wood boring insects which spend several years as white grubs before they gain enough energy to emerge as beetles. Females lay their eggs near decaying wood about one foot below ground and the developing larvae feed on this rotting wood for between three and seven years. There were no signs of any live stag beetles in the dusty wood pile- they must have long flown the nest.

Threat to habitat, such as the removal of decaying logs in parks and gardens, may have contributed to the decline of stag beetles. My house lies on the edge of woods which has plenty of fallen and decaying logs and I would be interested to discover if there are any stag beetle’s in the vicinity.
