I started off with nearly 1200 ova of 20 different species. I had a hatch rate of about 55%, which I find is about normal for this genus; two species proved to be completely infertile. I then had a success rate after hatching of about 21%, which is a lot better than last year's disastrous results, but not as good as some previous years. I always seem to do better with the Juglandaceae feeders than with those that feed on other tree families.
I ended up with 138 adults of 14 different species, but with 5 of these I only got three or fewer adults.
To think of you doing this now (for these past several years) is just amazing.
I cannot imagine there are many enthusiasts here in the US that undertake such an effort anymore.
Those Catocala maestosa which I see in the second photograph are an especially nice and BIG species to have gotten through to adults. One of the best amongst the "dark- winged" species for sure.
I keep all the ova in the fridge over winter and take them out when I think the buds are going to burst. The maestosa are unusual as all the other species hatch within 9-15 days of taking them out of the fridge, but maestosa took 35 days to hatch. It's the second time I've reared them and they were the same both times!
