Any example of squares appearing in nature?
I saw a ladybird not long agoiand it was dark brown with yellow squares on! Are there any other examples of a square/rectangular pattern appearing on living things?

Probably on the crystal level of things.

I cannot think of any and I was taught at school that there are no straight lines in nature.
Tortoise shells have square/rectangular markings.
It's unlikely that the laybird you saw actually had squares on it, I cannot think of any perfect cuboid shapes within nature, as far as I'm aware they are man made. As is previously mentioned, there are crystalline structres formed in nature which have straight edges, these are due to the attractions between different atoms forming the crystal.
There's no squares, that form any natural physical objects. The only squares you can see is squares formed as an ornament on the coloration of flowers, insects animals etc.
if you look at any animal with spots you will find a spot that is square if you look at enough animals.
Salt grains and similar have rectangular faces.
Other than that, most straight-edged shapes I can think of are hexagons (eg honeycombs, cool-cracked structures such as the Giant's Causeway).
certain gartr snakes, like the maritimes garter snake (T. sirtalis palustris) have squre markings along their sides. here is a picture:

Crystal structures. Bismuth and iron pyrite are the first that come to mind. But all crystal structures have angles that are perfect from a geometrical viewpoint.

Yes, plenty.. mostly plants. For example, the Seedbox (Ludwigia alternifolia) has a square shape on the cube-like seed capsule. http://cricket.biol.sc.edu/herb/ll/ludwi.
Many plants have square/rectangular seed capsules or rectangular flower petals.
Darn I forgot about Pyrite, its probably the best example of a cube in nature, I have a piece that is perfectly square/cubed. http://terra.geo.orst.edu/~taylore/miner.
