[3] Adalia bipunctata is a small Coccinellid that can feature any one of a large selection of red and black forms.

[4] Two-spotted lady beetles feed on aphids and other small insects.

The two-spotted lady beetle's life cycle starts with eggs that are usually laid in clutches.

The larva looks very different from an adult; it has an elongated, grey, soft body with six legs but no wings.

The cause of this anomaly is the presence of symbiotic bacteria living within the gametic cells of the female lady beetles.

This trait is associated with a variety of bacteria (Wolbachia,[6] Rickettsia,[7] and Spiroplasma[8]) which are present in between 0 and 20% of females, depending on locality.

[citation needed] The two-spot ladybird also carries a sexually transmitted infection in Central and Eastern Europe.

The two-spotted lady beetle was introduced into Australia specifically as a biological control agent.
