Guarding the eggs.

Known as the Small Brown Paper Wasp (Ropalidia revolutionalis), these social wasps are not overly aggressive like other social wasp species. Although they will attack if severely provoked, these wasps usually stand their ground on the nest and are not easily scared off.  When approached they will often make a display by buzzing their wings and shaking their bodies as a warning.

A Dipteran Duo

Here are two common species of Fly that I regularly see around the garden.  The first is the larger Grey-Striped Fly (Sarcophaga aurifrons), also known as a flesh fly.  I am unaware of the species of the second fly which was approximately 5-6 mm in length and seems to be a favorite target of the numerous jumping spiders that hunt on my window screens.  Both have amazingly complex and alien architecture when viewed up close.
