Lucanus capreolus - male - female

Lucanus capreolus - Male Female
Nashua, Hillsborough County, New Hampshire, USA
July 23, 2005
Size: 25 - 35 mm
This is the first date for this happy couple.

I found the female on the brick wall near my front door lights about midnight July 16, and tried night after night to lure a male with my UV lights/moth sheet, the female in a cage (so her pheromones would be carried on the breeze) and a sugar lure. No luck.

About 7:30 this evening I went out to take down the moth sheet and lights for use elsewhere on the next hot, humid night, and there on the moth sheet skirt, lying on his back, was a live male who felt some strange compulsion to show up at that moment. He looked like he'd just collided with the sheet and hadn't righted himself yet.

Was he attracted by traces of the female's phermones on the sheet or by something else?

Anyway, I introduced the two and they wasted little time getting to know each other. Eggs and larvae can't be far off!

No eggs, no larvae
Apparently the female was not impregnated by the male and never laid any eggs, although she survived the male by months. I sifted through the rotten hardwood pulp in the container she was in several times with no sign of eggs or larvae.

What kind of substrate do you use for breeding?
I use oak tree for the substrate along with hickory tree.
Here is the picture of the substrate with my larvae.

You know, Alan, it's been several years
and I just can't recall the source of my "breeding medium" other than what I wrote above. I'm glad to hear of your success.
