Tangle-veined Flies, named after the unusual wing venation visible in the second photo, are parasitoids of grasshoppers and beetles as larvae. Although I don’t think they’re going to get much of a meal off the grasshopper in the third photo. As adults, they’re pollinators, and are suitable equipped - Moegistorhynchus longirostris, from parts of South Africa, has a proboscis 80-100mm long, the longest of any fly.
There’s only 300 or so known species, but some are important controllers of grasshopper numbers.
A brown algae with a highly unusual fractal net-like morphology. IDed by Carolyn Ricci at the SA Herbarium, who do an outstanding range of PDFs I’ve found invaluable for identifying Australian macroalgae.
Found in warm and temperate seas worldwide, but this was the first time I’ve ever seen anything like it. The name means ‘latticed water-lattice’, to really hammer the point home. It’s often found growing epiphytically on another common brown algae, the blob-like Colpomenia sinuosa, which it rather resembles apart from all the holes. (Speaking of which, I hope this doesn’t trigger anybody’s tryptophobia - I made the mistake of showing this photo to a friend who was once extremely ill with a high fever, and was hallucinating patterns like this.)
Brought in to the WA Naturalist’s Club meeting by one of the members, to compliment the talk on Marine Plants I was giving. Naturally I covered all the species I’ve discussed on Tumblr previously.
Apparently it’s edible, and makes an interesting addition to salads.
Identified for and photographed by Lesley Brooker, here in Perth, based on the resemblance to the more common Ocirrhoe genus of small green stink bugs.
