The ladybird (also known as the ladybug) is a small colourful beetle found all around the world.There are thought to be more than 5,000 different species of ladybird in the world, with more than 450 species found in North America alone.The ladybird is best known for it's spotted body (normally red and black, but often orange and yellow are found), and their ability to rid gardens of their aphid pests affectively.fter a couple of weeks, the ladybird larvae evolves into a ladybird pupa which is about the same size and colour as an adult ladybird but has a protective layer surrounding it, until it has developed it's wings. Once the ladybird pupa has developed, it breaks out of the skin surrounding it to become an adult ladybird.
'Threat': The harlequin ladybird. The harlequin ladybird-an aggressive, toxic invader that has colonised Britain in just four years-is threatening more than 1,000 native species, scientists say.Since it arrived in the South of England in 2005, the bug has spread at an incredible rate and is now found everywhere from Essex to Orkney.ow a new study claims that the fast-breeding ladybirds are putting hundreds of native British insects, parasites and fungi at risk. Although the harlequin is unlikely to drive native ladybirds to extinction, the invader may become so dominant it is the only ladybird people see.
