purple beetle

Prepare a picture of/book about/a toy purple beetle in advance, as well as toys or a picture of insects.

Say: Look at these creatures.(Show a picture of insects) these are insects.

Remember to be classified as an insect, an organism should have:

A hard shell-like covering its body. Three main body parts: head, thorax, and abdomen. A pair of antennas. Three pairs of legs.( They use the legs for walking, but sometimes an insect may have a pair of legs that are specially designed for jumping) and two

pairs of wings. Insects are part of a bigger animal group called arthropods. All insects grow from eggs. They go through various stages called metamorphosis.

Now, (show a picture of a purple beetle) Say: Look at this insect. (Point to the beetle) It´s a purple beetle! Over 300,000 species of beetles live on the earth. Beetles live everywhere – from hot deserts to the polar ice caps. Beetles have a hard shell and four wings. Some beetles cause a lot of damage by eating crops, wood and food. Others help us by pollinating crops or eating harmful insects. Beetles come in a lot of colors. Beetles can be bright yellow, green, red, orange or purple. They can have stripes or spots. The purple ground beetles are black with a metallic purple sheen, especially around the flattened edges of their fused wing cases. They have a head, thorax, and abdomen, and six legs. Their bodies tend to be very solid and tough. They have chewing mouthparts and powerful jaws. Adult beetles have modified wings: the first pair of wings is small and very hard, and acts as a protective covering for the second pair of wings. Many beetles fly with the second pair of wings. (Let´s spread our hands and fly like beetles). Go back to the picture of the beetle. Say: let’s find beetle’s body parts. This is its head, eyes, nose, mouth, abdomen, antennas, legs:( Count with me,baby) 1,2,3,4,5,6; these are its wings. The purple beetle is a common beetle found in gardens, farmland and meadows. Purple beetles are active, nocturnal predators, chasing and catching smaller invertebrates; they are particularly helpful to gardeners as they prey on many pest species such as slugs. They can often be found resting during the day under logs and stones and in leaf litter.

Purple beetles go through metamorphosis just like all insects. Adult females lay their eggs in soil and they hatch into larvae. The larvae look like ugly little worms. They’re sometimes called grubs. Later, beetles enter a pupa stage and transform into adult beetles that become active predators themselves.

Purple beetles are living things and need energy to survive. Most species that live in the soil like to eat slugs, decaying wood, decaying leaves and other rotting plant material. Since purple beetles feed on both plants and animals; they are considered omnivores. We need to take care of purple beetles and treat them with respect because they are living things just like us, people.
