Lynx spiders

lynx-spiders

Lynx spiders come from the family Oxyopidae. As my supervisor likes to say, they are like a cross between jumping spiders and wolf spiders. As you can imagine this makes them very hard to catch! They don’t build a web to catch prey so they have good eye sight (like jumping spiders) for catching insects […]

Theridiidae

Theridiidae is a very large family of spiders (Wikipedia tells me there are over 2200 species). One famous example is the Hawiian happy face spider, which is cute AND has an interesting evolutionary history (it is only found in certain locations along the Hawaiian chain of islands). The most obvious Theridiid species from Australia is […]

Jumping spiders

Jumping Spider, Botanic Gardens Sydney

  I can understand why jumping spiders (Family: Salticidae) are often the poster-boys for spider enthusiasts (see Misunderstood Spider), they are so cute and charismatic it’s hard not to love them. They are also the family which Peacock spiders belong to, and if you haven’t heard of them you really need to watch this YouTube […]

Net casting spider

As the first name suggests, they hold a stretch of web between their front legs and throw it at their prey. I’ve spent ages sitting watching them, waiting to see the action, but no luck yet. […]

Unique species of crab spider

This is one of my favorite finds so far: Thomisidae are commonly known as crab spiders. They sit on flowers waiting for their prey and are famous for their bright colours under UV light (this is thought to help attract prey). Crab spiders normally look much more like this, but there is often a lot […]

Argiope keyserlingi

Here is a spider most people in Sydney will recognise, the St Andrews cross. The female is very distinctive with yellow stripes on her abdomen and a cross in the middle of her web, so I assumed this ID would be simple. But then I came across these two. At first glance I assumed they […]

The scary world of spider taxonomy

My ID work station

I have to admit, there is one aspect of this research that really scared me… it wasn’t the collecting of spiders that worried me (I love the little guys and I’m yet to find one who is willing to bite me), it was the classification of them! There are more than 40,000 species of spiders […]
