Life cycle: It usually takes from 4 – 19 days for the eggs to hatch. Plant2pollinator support materials consists of keys, observation matrices, plant biology facts, and teaching ideas for field studies. Frogs, tadpoles and fish will be consumed as much as invertebrate animals. They use light reflected from the water to find ponds. Pupation occurs in the soil or under bark, or in some species in rotting wood. Beetle bodies are divided into three (3) parts: head, thorax, and abdomen.
