It's the same as insects that have evolved to taste foul. The individual insect does not survive bring chewed on, but predators only eat one before learning their lesson, meaning any offspring they already have are less likely to be eaten. In this case it would be relying more on predators seeing one of their own blown to bits, which might suggest that their primary predators in the past were group hunters ,or likely to be present in numbers at any rate.
