More invertebrates (and a bird)

 On 27 January we found a few interesting invertebrates.  This began in our garden finding this colourful jobbie crawling around behind the shed,

iNaturalist.org identified this as a Blue Ant (Diamma bicolor) which has been confirmed by some fleshware associated with that facility.  It's more of an ain't than an ant, as it is actually a wingless flower wasp.  The females hunt mole crickets in which they lay their eggs,

We then we to Bastion Point, following up a further sighting of Southern Emuwrens in that area.  We were unlucky with the wrens but there was plenty of insect activity on the Sea Rocket Calkile maritma.   This first butterfly in an Australian Painted Lady Vanessa kershawi.
The Cabbage Whites Pieris rapae were in swarms, as they seem to be everywhere this year.
While I continued the fruitless search for Emuwrens Frances went to rocks exposed by a low tide  and found this beastie.  It is a Calloused Keyhole Limpet Amblychilepas nigrita and referring to our book on Coffin Bay (in SA but it is a mine of information on our marine life) says that it's body is far too big to fit under the shell.
Here are its antennae.
This looks like a mini-lobster but iNaturalist has been consulted.  It was not well.
An Eastern Reef Heron was also exploring the reef.  No idea why it had its beak open.

When we got home I had more information about another site for Emuwrens: the marsh opposite our street.  I managed to spot a male!  But be warned: wear wellies not shorts and don't think about Tiger Snakes.
