Many butterflies taste with their feet to find out whether the leaf they sit on is good to lay eggs on to be their caterpillars' food or not.
Skeletons - Exoskeleton - Related to Crabs and Lobsters - Arthropods
Butterflies and insects have their skeletons on the outside of their bodies, called the exoskeleton. This protects the insect and keeps water inside their bodies so they don’t dry out. Butterflies are related to crabs and lobsters! Why? Because those sea creatures also have skeletons on the outside of their bodies! Butterflies are arthropods.
There are about 28,000 known Butterfly species throughout the world.
Butterflies are cold blooded and don't produce metabolic heat like humans, they must rely on the sun to raise their body temperature to be able to move about. Many bask with wings open - others close their wings together.
To mate the male or female will perform courtship movements and release pheromones. The pair of butterflies then turn abdomen to abdomen and mate for an hour or more. Sometimes they will even fly around with either the male of female dangling. The male butterfly will pass the female a sperm packet that is used for fertilizing eggs.
A butterfly can lay up to 500 eggs
Some butterflies can reach speeds of up to 2 miles per hour. Butterflies aren't able to fly if their body temperature is less than 86 degrees.
Butterfly - So Named
Past beliefs have it that the word butterfly is derived from the expression "butter-coloured fly", a term which may have been applied to the Brimstone a yellow butterfly and one of Britain's most well known - a species which hibernates as an adult and, as such, spends the majority of its life as an adult butterfly.
Butterfly Sight - Ultra Violet - up to 6000 lenses
Butterflies can see ultraviolet light - which humans cannot see - it makes the markings on flowers very vivid to them and guides them to the nectar tubes. Some butterflies have ultraviolet markings on their own wings which are visible only to other butterflies. Butterflies have compound eyes each of which can consist of up to 6,000 individual lenses.
Butterflies aren't able to hear - they can feel vibration which is useful when hiding from predators
Communication Amongst The Butterflies
Most butterflies communicate using chemical signals - male butterflies produce pheromones - which trigger a welcoming response from others of the same species. Occasion a butterfly will in effect use sound as they "rustle" their wings
Antarctica - No Butterflies
The only continent where no butterflies can be found is Antarctica
