How do butterflies reproduce? • If you see two adult butterflies with their abdomens linked tailto-tail, they are mating. • The male grasps the female and deposits a sperm packet, which fertilizes the female's eggs. • The butterflies can fly while mating, but they usually avoid moving unless they are disturbed.
How do caterpillars breathe? • There is an oval opening called a 'spiracle' on each side of each segment. • These are connected to a tube, the 'trachea. ' • As the caterpillar moves, air is pumped into the trachea, causing oxygen to be taken in and carbon dioxide to be pushed out. • Caterpillars do not actually breathe as we do, but air is exhanged by the compression and extension of each segment.
Why are some butterflies brightly colored and others are not? • Butterflies who might taste good to predators need to hide from therefore they may be camouflaged. • Butterflies that taste bad or are toxic to predators have no need to hide. • These butterflies display bright warning colors as a way to remind predators that they taste bad or are toxic. • Some butterflies also use their colors to attract mates.
Why are butterflies important? • They are important as plant pollinators and at that, they are second only to the bees. • They are also very sensitive to the environment and thus are good indicators in assessing how healthy or unhealthy conditions we are living in. • They also have their own important place in the ecosystem like all animals do. • And of course the joy and the delight we can have from watching these beautiful creatures is priceless.
What is the difference between butterflies and moths? • Butterflies are day-flying while moths generally fly at night. • However, there are moths that are active during the day that could easily pass for butterflies. • The best feature to look at is their antennae: Butterflies always have threadlike antennae that club tipped. • Moths can have many types of antennae: feathery, hairy, threadlike or filamentous, but without the clubbed tips.
