Not since morphing, Jen. And they were never as voracious as the H. tokyoensis. I ended up with too many of them (35+) as there so many in the egg sac to begin with. I've just found a good home for 20 of them!
By the way, these particular ones are a bit unique as they come from the tiny island of Iki (notorious in the past for its lethal dolphin roundups) of Nagasaki Prefecture. While this species is widespread in Japan, the ones on Iki seem closely related to H.tsuensis on nearby Tsushima Island (or so I was recently told).
