Blackleg is a highly fatal disease of young cattle caused by the spore forming, rod shaped, gas producing bacteria Clostridium chauvoei. The spores of the organism can live in the soil for many years. The bacteria enters the calf by ingestion and then gains entrance to the body through small punctures in the mucous membrane of the digestive tract.
Ladybugs eat aphids (green insects that live mainly on roses) and  drink water. Sometimes they consume pollen and nectar from plants  to save up for winter. Some types of laâ¦dybugs eat grass and leaves.  Usaly orange or yellow ladybugs eat nectar and pollen and drink  water and sometimes they eat grass.
Some beetles are parasitic while others hunt soft-bodied insects such as caterpillars and grubs. The dung beetle eats exactly what its name suggests. The lady beetle (better known as a ladybug) feeds off of lice-sized aphids on plants, keeping human vegetation safe from these types of destructive insects. But then there are beetle species like the carpet beetle, which can invade your home and eat through your upholstery, clothing and more.
