How does a frog capture and swallow insects?

The frog retracts its eyeballs into the mouth cavity to push the insect down its throat. This motion produces a shearing force parallel to the tongue that is high enough to turn the saliva thin and watery, and the insect is released and swallowed.

Frog's tongues are attached to the front of their mouths rather than at the back like humans. When a frog catches an insect it throws Frogs do need access to water for hydration, but as far as I'm aware; any frog limited to only water (aqua), and deprived of the same type of oxygenated atmosphere or air (aer) that we breathe; will die in relatively short order.
Frogs typically only really eat live (or moving) prey.
Arthropods (insects, etc.), small mammals (mice, etc.), small lizards (skinks, geckos, etc.), small freshwater shrimp or fish (perch, guppys, etc.), sometimes even smaller frogs.
Basically, if it's:
Big enough that the frog can see it;
Small enough to fit in its mouth;
And it moves;
It's a goner. Pretty much any frog with a healthy appetite will hunt it down.
I recommend:
Flys
Moths
Crickets
Katydids
Wood-Lice
Cockroaches
Darkling Beetles
Various worms, grubs, larvae
Springtails (for small frogs and froglets)
