Life cycle of Lucanus elaphus

[nurunuru]

I'm hoping someone here with experience of keeping Lucanus elaphus can shed some light on how long they tend to live in the imago stage, as the information I've found online has been very conflicting.

Supposedly L1 to L3 takes anywhere from 1 year to several years, pupal stage lasts 7 to 9 months, and then the imago stage either lasts 1 month or 2+ years depending on who you trust. Does anyone have some more reliable information they could share?

Mine stayed dormant for about 6 month. Male lived about 2 month and female lived about 3 month.

P.S. They became adult on October.

...and then the imago stage either lasts 1 month or 2+ years depending on who you trust.

The answer depends on if you find or rear them but anything much over twelve months is fantasy.

Thanks very much. Two years plus for the imago stage did seem too much to hope for; even if it is possible with some other Lucanidae.
