Squeaking Cockroaches

I disturbed dozens of these insects while cutting old logs for the fireplace. The adults are about 40mm long and sometimes squirt a yellow liquid if you touch them. I thought they were woodlice and read that those crustaceans are edible and one can find wood-louse sauce recipes on the internet. But the lower one in the photograph looks more like a large roach, not a woodlouse at all, but they were all living together. I'll have to count their legs... I did. See next entry. I guess the lower one is a male of the same species.
