Two photos of the Christmas Jewel Spider on illustrated polaroids. The first photo on the left shows the spider’s underside as the stem its sitting on is being held by two fingers. It is a tiny orbweaver, much smaller than the visible fingernail, and is mostly black with mottled red and yellow. Its abdomen has symmetrical spines. The second photo shows it from the front, its prosoma is all black, its legs are red, and its abdomen is black with symmetrical white markings. The abdomen’s spines are fully black.
A photo of a melanistic Christmas Jewel Spider on an illustrated polaroid. The spider is jet black all over, but otherwise has the exact same appearance (ie size and shape) as the non-melanistic variant. This photo is dorsal, showing the spider from above.
Two screenshots from the iNaturalist website on illustrated polaroids. The first, on the left, shows the seasonality data of the Christmas Jewel Spider. It has a sharp peak in abundance from November through to January, where it steadily declines until it is nearly absent from June to September. The second image is a map of Australia, with orange pixels representing a heatmap of abundance records on iNaturalist. It is found all around Australia’s coastal communities and somewhat inland, with a handful of observations in central Australia. There are few records in the country’s north, and a high concentration of records in South-Western Australia, and around the South-Eastern region. There are some records in East Tasmania.
🖤🤍❤️Now this one’s a real gem! In the warmer months, keep an eye out for the tiny Christmas Jewel #Spider (Austracantha minax)!💎🔬
This harmless tiny #arachnid is the only member of its genus, and is endemic to #Australia! 🇦🇺🕸️In #autumn you might even see one expressing the rare #melanistic form! 🍂
