Although, bats and moths certainly had an evolutionary arms race.Bats used echo location to hunt moths and moths responded by adapting the capacity to detect those sonic pulses.So, bats developed new frequencies that the moths couldn't detect as well,but new moths were able to transmit sounds that threw off the bats' measurements, or signaled that the moths were poisonous.Regardless of how fiercely bats and moths have tried to outgun each other, that can't have pushed butterflies to the daytime,since bats didn't develop echolocation until 50 million years after butterflies showed up.It's most likely that butterflies moved into the daytime to find more nectar from flowers that open during that time.Eventually, butterflies shed their drab ancestral coloring and evolved coats of vibrant colorsthat advertise to mates and also send warnings to predators.
