The bright colours warn potential
enemies such as predators that ladybirds are not
at all tasty. This so called "warning colouration" reminds
predators of previous distasteful encounters with
ladybirds!

This is called "reflex blood".
It is very strong smelling and contains the toxins
which make ladybirds off-putting to so many predators.
Ladybirds do not die after producing reflex blood;
it is part of their warning system.

| Ladybird adults spend the cold winter months
in a dormant state. As the weather warms up in
late February and March the adults begin to get
active and search for early aphids to eat. The
adults mate in the spring and the females lay
eggs during the spring and early summer. This
generation of adults then dies as the new generation
hatches out. |

The newly emerged larvae (immature
ladybirds) do not look anything like their
parents; they are black and grub-like. During
this stage they eat lots and shed their skin
three times before pupating. The pupa stage
lasts about a week and from this the new adult
emerges. The new adults must eat lots of aphids
to build up reserves to see them through the
winter months.
