Pupae are rather fragile but I have reared many to adulthood. At present these are loose in a sealed container with plenty of small, moist scraps of their white-rot aspen wood. There are certainly more of them pupating inside the larger-sized chunks of wood in the same container, so even if all the loose ones died I should still get some adults for final ID confirmation and photos.

Tom Murray has also had good success rearing larvae during the past year and we are steadily building a database of beetle lifecycle documentation.
