Adult butterflies, as well as caterpillars, breathe through a series of tiny openings along the sides of their bodies, called "spiracles." From each spiracle, a tube called a "trachea" carries oxygen into the body. Butterflies don't have noses and lungs as we do. Butterflies "smell" with their antennae.
Butterflies communicate mostly through chemical signals. Males produce 'pheromones' to attract females. A few species communicate with sound. For example, the male Cracker Butterfly can produce noises with its wings.
Butterflies and moths both belong to a group of insects called "lepidoptera", meaning that they have wings covered with scales. They are related in many ways. Butterflies are generally brightly-colored while moths are generally drab, though they are many dramatic exceptions to this. Almost all butterflies are active during the day, and most (but by no means all) moths are active at night. A good way to tell the difference is by their antennae. Butterfly antennae are shaped somewhat like a golf club, with a long shaft. Most moths have either simple filaments tapering to a point, or complicated affairs with many cross-filaments.
Unlike Asian elephants, in which only males have tusks, both male and female African elephants are tusked. However, due to the hunting pressure on tusked animals brought about by poaching for ivory, tusklessness is an increasingly common condition in African elephants.
Elephants have little in common with cattle, but they share with them the names for adult male (bull), adult female (cow) and juvenile (calf). Even their collective noun is the same: a herd of elephants.
The trunk combines both nose and upper lip and transforms them into a single powerful organ that is able to touch, grasp and smell. It is strong enough to uproot a tree, sensitive enough to pick up a pea-sized fruit from the ground, and long enough to reach foliage high in the trees. The trunk is also used to drink by sucking up water and squirting it into the mouth. Finally, elephants use their trunks for greeting, caressing, threatening, and throwing dust over the body.
The elephant's trunk has about 15,000 muscles and it takes baby elephants quite some time to learn to master its use.
All cut flowers must be kept moist constantly to sustain their fresh appearance for as long as possible. If your flowers are placed in a container with floral foam make sure to add water daily, mixed with soluable plant food suitable for flowers . Pour the mixture in the centre of the foam so as not to overflow. When receiving flowers in a vase make sure the water is clear and contains plant food. When first placing cut flowers in water be sure to cut the base of each stem on an angle and under water. This assures a greater surface area for water/nutrient absorption and it eliminates osmotic shock by eliminating air contact with the absorbing stem cells.
Depending on the flower variety itself, fresh cut flowers can last from as little as a few days up to three weeks. Tulips and irises last only a few days while some tropicals will last weeks. Proper care and of course starting with fresh healthy stock will assure maximum life span.
