Ladybirds

Ladybirds or Ladybugs are insects from a family of coccinellidae. "Ladybirds" derives from Britain and the insects are known as the lady beetle. The word Coccinellid is a Latin word means scarlet

Most ladybugs have oval - dome shaped bodies with six shorts legs. They can have spots, stripes or no marking at all, according to their species. Seven spotted coccinellids are red or orange with three spots on each side and one in the middle; they have a black head with white patches on each side.

Ladybirds are known as predators of aphids and scale insects. They are purely carnivorous but some species in the sub family Epilachninal are herbivores, and can be very destructive agricultural pests. They can damage the harvests.

Ladybugs are bird's prey besides frogs, wasps, spiders and dragonflies. Their bright colour discourage some potential predators to attack them. This phenomenon is called aposematism. The predators learn by experience that 'good looking prey', associates to bad taste. These insects produces an alicalloid toxin when the predators attack them.

Ladybirds bite people and cause allergic reactions. In the grape orchard, they can cause the wine's production becomes poor.

Clown Fish

            The clown fish also known as the anemone fish, is a small species of fish that is found around tropical coral reefs. The most commonly known species of clown fish is orange with white markings. But, clown fish can be found in many different colours and can also differ in shape.

Clown fish inhabit a single sea anemone in groups that include the breeding male and female and a number of younger male clown fish. All clown fish are born male and develop female reproductive organs when needed. When the female in the sea anemone groups dies, the dominant male becomes female and breeds with one of the males that is inhabiting the same sea anemone.

Female clown fish lay their eggs on a flat surface, close to the sea anemone which they inhabit. They can lay hundreds or thousands of eggs at one time depending on the species. The female lay their eggs around the same time as a full moon and the males guard the eggs until they hatch just over a week later.

Clown fish eat both plants and animals. They eat a wide range of food such as algae, plankton, molluscs, and small crustaceans. Their diet is, however, largely dependent on the species of clown fish and what food is available in the area which they inhabit.

Due to their small size, clown fish are preyed upon by a number of predators, but it can be difficult to catch since they often retreat into the safety of the sea anemone. Large species of fish, sharks and eels are the main predators of clown fish in the water. But, human is the biggest overall threat as they are caught to keep in tanks and aquariums.
