Hi Andrew,

If you're planning on using the larvae for live fish food, they are probably okay if the fish find them tasty. The cabbage white butterfly feeds on cruciferous plants (mustard family) which do not have poisonous alkaloids in them, so it is probably safe. However they might not taste good to your fish.

If they do like the worms use as a treat not a staple food.

Google search for "cabbage butterfly poisonous" yielded this:

Quote:
The entire life history of the butterfly is poisonous to varying degrees. The larval foodplants contain mustard glycosides which the larva is able to assimilate and convert to mustard oils (isothiocyanate irritant poisons) to be retained in its body as a protection against predation. These poisons can be passed on to the pupa and the adult butterfly. The poisons are also probably passed onto the eggs by the female adult butterfly to complete the cycle. These poisons are usually in sufficient concentrations to only sicken the vertebrate predators or at least taste unpalatable, so that the predators can learn from the mistake and pass on the experience. They are not meant to cause death as this would likely result in larger numbers of the insect being killed.

Keep researching, though; I have no idea how scientifically valid this page is.

IIRC from my biology lectures, the caterpillar feeds on a plant that contains a glycoside that will taste "bad" to the predator (blue jays, in Canada at least). It won't be lethal to a bird, but then a fish is an entirely different question, so I would avoid feeding them to your fish altogether
