Flower spider on mint blossom

Zygometis lactea: flower spider

The mint has almost finished flowering, which is good as then I can cut it all back. I’ve never let it get all long and scraggly before, but there were so many insects enjoying it that I didn’t have the heart to trim it.

The other day, I spotted this tiny white spider. Googling has revealed it to be a Flower Spider.

Today, my thoughts are with my good friend and cousin, Sue. Her mum will be laid to rest this afternoon. I have never met Sue, in person, but we email each other fairly constantly since we met through family history research, as well as chatting here in comments.  Sue, deepest sympathy to you and yours.  ❤

Icky Sawfly Larvae

This is from a forestry website – full info and more photos can be seen there.

spitfire 3I thought I would delight  bore educate enlighten you with some  information about the grubs I pictured yesterday: Spitfire caterpillars,  larvae of our Australian native Steel Blue Sawfly (Order Hymenoptera). I’ve gathered information from Museum Victoria, Wikipedia, CSIRO, a Forestry site,  and a South Australian Government website.

The sawfly is a  wasp, related to the Cherry and Pear Slug.  It has a stocky body, usually a dark metallic blue, and does not sting.  It has a double pair of wings with a span of about four centimetres.  The adults are rarely seen, and spend their time hanging around their host tree.  The sawfly gets its name from the saw-like ovipositor of the female. She opens holes in the underside of the leaf and lays her eggs.

The Spitfire larvae, about 8 centimetres long, love their tucker.  Mainly active around late winter and spring, they sprawl around enmasse during the day, but at night they disport around the tree chomping gum leaves.  They can gather into groups of as many as two hundred.spitfire 1When threatened, they raise their heads and exude a yellow-green liquid, strongly flavoured by eucalyptus oil extracted from the gum leaves.

 They did this to me, the other day. About ten of them all jerked their heads up at the same instant. Needless to say, I leapt back and didn’t bother them again. I have no idea if they do actually do spit the stuff, and I didn’t want to take the risk of anything nasty dropping in my face.

Eventually, about mid spring, the larvae are ready to pupate. Still enmasse, they make their way into the ground, burrow in several centimetres, and make themselves a strong paper-like cocoon. It might take two or three years before the adult emerges.

I intended to take fresh photos today, but the bunch had moved up the branch overnight (featured photo). I think they are fascinating, and it will be interesting to see if they do survive to pupate. Small groups of twenty or so do not always survive.  A few birds, currawongs and cuckoo-shrikes will eat them. Good luck to them!
