Holly blue caterpillars make a sweet liquid called honeydew, which ants milk. Orange tips have bright orange tips to their wings. Hairstreak butterflies have a false head on their hind wings. Birds peck at this, leaving the real head alone. Male queen butterflies stroke the female' s antennae with hair brushes on their abdomen to prepare her for mating.
Tiger moths emit high-pitched clicks at night to warn bats they taste bad.
Woolly bear moths are edible but emit the same clicks. The biggest butterfly is the Queen Alexandra's birdwing, which has wings up to 28cm across. Butterflies sip nectar from flowers through a straw-like tube called a proboscis.
