Hi John.

I am all too familiar with this. They swallow it whole. What happens is they aren't use to the dubia's strong grip and filaments and it startles them. They will either spit it out all together, move it around until they are more comfortable with it or hold pressure on it until it quits moving. We see this all the time with ours. All you have to do is throw it back in front of them. Chances are the second attempt it will go in different and they will swallow it with no problems,
