I found this guy crawling around on the street outside of our house in West Tokyo. He struggled mightily when I plucked him from certain doom by footstep, apparently unaware of our fine tradition of bringing large insects into the house and feeding them before setting them free.
Kabuto-mushi (rhinocerous beetles) like this love tree sap, particularly that of the kunugi, or sawtooth oak. In fact, the places they and other bugs accumulate on oak trees in summer are colloquially referred to as konchu no sakaba, or "bug bars." Perhaps that's where Hiroko hit on the idea of drizzling maple syrup on gauze as a little treat for him: "It'll be the beetle equivalent of single malt!"
She was right. The minute we put him near the gauze, he took two steps, halted, and plopped his face into the syrup, totally unmoving. As I suppose I would if after being captured by enormous beetle-creatures I was presented with a tub of Glenfiddich.
An hour and a half later, we checked and he was still happily sucking away. So we built a little house for him out of a plastic bottle. When I woke up this morning, he was still in there, apparently sound asleep, clutching the gauze to his chest like a baby blanket. Looks like we made a new friend.
