Dubias

[unkempt1]

My frog is weird with dubia. When I tong feed them to him, he pretty much instantly gulps them down. But then he spits half of them out, waits with them halfway in his mouth, and gulps them down again. Maybe he's debating on eating them but then can't resist the urge?

Its pretty comical. I can't think of a time where he didn't do that. Oh, and he doesn't do it with crickets.

I looked into the legality of cockroaches in Canada a couple of years ago and at the time, virtually all tropical ("exotic") cockroaches and similar arthropods were coined illegal unless kept in an approved research or educational facility. There are a couple of conversations floating around with Douglas Parker of the CFIA.

You should be able to use local fauna... if you felt comfortable rearing the notorious german roach (Blatella germanica) you could isolate F1 generations and cull the founding population to eliminate issues associated with wild caught insects. Particularly important for this pest species that is notorious for finding its way into rather unsanitary locations.

Oh yeah lol mine do this too! I'm pretty sure they are just readjusting the roach to go down in a particular direction (easier to swallow). My big Bertha also likes to chomp on it before she swallows so u get to hear that awesome crunch sound every time she eats one nomnomnom.
