Vida's Sheep Jumping Spider: researchers believe that these tiny spiders developed their "woolly" appearance as a way to mimic lacewing larvae or scale insects

The scientific name for this species is Oviballus vidae, but it has also been referred to as the "sheepy jumping spider" or "Vida's jumping spider." It was discovered in 2015, and first described (in a formal context) back in 2020.

As this article (PDF) describes:

Recently, two new salticids, R. legitima and Oviballus vidae were described from South Africa, and suggested to be mimics of either scale insects (Hemiptera: Coccoidea) or lacewing larvae (Neuroptera: Chrysopidae), due to their white colouration and the presence of peculiar tufts of white setae on the body.

The possibility of [scale insects] being the model is supported by Oviballus vidae being regularly collected from plants with woolly scales, although the movements of O. vidae quite closely resemble those of chrysopid larvae.

In fact, a fourth species of possible scale mimic, a new Rhene species, was recently discovered in a collection of salticids from southern Mozambique, indicating that this phenomenon may be more widespread than has previously been known or even suspected.

O. vidae was named after Vida van der Walt, the photographer who captured some of the first images of these spiders back in 2015, just after the species was discovered by Dr. Galina Azarkina. Vida van der Walt also took the photographs that appear in this post.

They're done!

I'm calling this batch Midnight Auroras. I was a little worried if their eyes wouldn't stand our from the dark yarn, but after testing it, they came out pretty cute!

Also experimenting with some background pieces instead of the base gray... photography is not my strong suit lmao. Though the morning tornado-warning weather gave me some good lighting, at least.

Plus it looks a little better in the closeups. I think.

As always they are up for adoption on my etsy page!

Prancing Peacock Spiders

Maratus volans is perhaps the most widely known member of the genus Maratus, also known as peacock spiders– part of the jumping spider family– which contains 108 recognised species. Maratus volans is common across Australia and the island of Tasmania, and occur in a variety of habitats. They are most commonly found among leaf litter and dry vegetation, especially in dunes, grasslands, and sparse deciduous forests.

Peacock spiders like M. volans are extraordinarily small; both sexes only reach about 5 mm (0.19 in) in length. Members of the Maratus genus are famous for the male’s coloration, and M. volans is no exception; the abdomen is covered in brightly colored microscopic scales or modified hair which they can unfold for mating displays. Some males can also change the color of their scales, and the hairs can reflect both visible and ultraviolet light. Female M. volans lack this distinctive coloration, and are a drab grayish brown.

Reproduction for M. volans occurs in the spring, from August to December. During this period, males will approach females and raise their patterned abdomens and third pair of legs for display. He then approaches, vibrating the fan-like tail, and dances from side to side. If a female is receptive, he then mounts her; if not, she may attempt to attack and feed on him. This may also occur post-copulation. In December, the female creates a nest in a warm hollow in the ground where she lays her eggs. Each cluch contains between 6 and 15 eggs, though females typically lay several clutches. Male M. volans hatch the following August, while females typically hatch in September. Both sexes mature quickly and typically only live about a year.

Like other jumping spiders, peacock spiders like M. volans do not weave webs. Instead, they hunt during the day time using their highly developed eyesight. These spiders are also able to jump over 40 times their body length, which allows them to pounce on unsuspecting prey like flies, moths, ants, crickets, and other, much larger spiders. Other spiders are also common predators of M. volans, as well as wasps, birds, frogs, and lizards.

Conservation status: None of the Maratus species have been evaluated by the IUCN. However, it is generally accepted that they are threatened by habitat destruction, like many other insects.

Image ID: a close-up picture of a spider. It’s looking up at the person taking the photo with its head tilted. It’s mostly mottled brown with two iridescent green patches on the front of its head. It has 4 round eyes, with the center pair being larger than the outer two. You can kind of see a silhouette of a person in the reflection of its eyes. It has little tufts of hair all of its body, with two larger tufts on either side of its head. Frankly, it’s adorable. /End ID

I'd like this a lot

glimpse into my beautiful imaginary world where arthropods are really big and we domesticated them

edit: people are starting to say some "my worst nightmare" or "eeeww no that one is yucky and scary" comments on this like they do on any bug post and id like to say. it's fine if you don't like bugs it's fine if you're scared of bugs but don't put that on MY post clearly talking about how much i like them and how cute i think they are. you can make your own damn post about how much you hate wasps or spiders or whatever. i'm blocking people who make these kinds of comments.

Been practicing drawing jumping spiders. I still have quite a ways to go in drawing one of my favorite animals, but I’m still pretty proud of how this quick little drawing turned out.
