Odd looking insect

This is the stick worm caterpillar that hides itself in the sticks to avoid predators.

The caterpillars make a protective hull from grass, sticks or thorns in this case.

Later it transforms into a moth.

Oddly coloured eggs

Chicken egg colours explained:

  • White eggs: all eggshells are made of calcium carbonate and the white ones have no pigment added
  • Brown eggs: caused by protoporphyrin IX, from the hen’s haemoglobin, and is coated on the outside of the egg as it moves through the oviduct
  • Blue eggs: have the pigment oocyanin, which does permeate the shell, so the blue colouring will be all the way through
  • Green eggs: if a brown layer and a blue layer are crossbred, chances are you will get a green egg when the protoporphyrin IX layer is deposited over the blue oocyanin shell
  • Pink eggs: comes from the bloom or cuticle, a natural coating that seals the eggshell’s pores. The bloom is often washed off before eggs are sold commercially
  • Speckled eggs: can be laid by any hen with pigmented shells and comes from the egg rotating slower than normal during the pigmenting stage
