Bug of the Week: Sunspiders

“What is it?” the woman asked, and handed me this creature. “Cool,” I said, which is probably not what most people would say :-).

It turns out I knew exactly what it was. This fearsome-looking invertebrate has a number of common names, such as sunspider, windscorpion, camel spider, solfugid or solpugid. It belongs to the order Solifugae, which contains approximately 12 families.

Sunspiders are unique to deserts. They are not true spiders nor scorpions, but they are arachnids. They have eight legs, plus a pair of leg-like appendages in the front called pedipalps. The pedipalps have sensory functions, like the antennae of insects, and also hold and manipulate food items.

The features that catch most people’s attention, however, are the large jaws or chelicerae. They use the chelicerae to catch insects and other small animals.

Can you see the dark spots in the middle of the head behind the chelicerae? Those are the eyes.

Sunspiders hunt at night, like most other arachnids. They can move very quickly to grab prey. They are also thought to be scavengers, eating dead insects as well as live ones.

The good news is that sunspiders are not venomous and most of the small ones are pretty much harmless to humans. They are likely to run away if startled. In fact, little is known about these shy desert inhabitants.

Have you ever seen a sunspider?

Author Sandra Markle has a new children’s picture book, with the slightly misleading title:  Wind Scorpions: Killer Jaws (Arachnid World). (I guess they are killer jaws if you are a cricket.)

Bug of the Week: Baby Black Widows

Have you ever seen baby black widows that have just hatched from their eggs? We did yesterday.

It turns out that immature black widow spiders are not black at all. They are brown and white.

They do show one characteristic of their parents, however. They hang upside down from their webs.

The babies will string out single strands of silk and quickly disperse from where they hatched. In a few hours, you won’t know they were even around.

Where did the babies come from? Female black widows lay their eggs in drop-shaped silken bags hidden around flower pots or boards. They will then guard the egg sacs until the little ones hatch.

Now I need to go out and try to get a photograph of the spider wasp that was hunting for spiders this morning. I think she was looking for something bigger than those babies.

Bug of the Week: Jumping Spider

After all the flies for the last few weeks, I thought it was time for a spider.

I found this little jumping spider, Family Salticidae.

I was hoping it would turn and look at me, because jumping spiders have such large eyes in comparison to the rest of their bodies; they are really dramatic. I don’t usually try to pose my subjects, so I guess the silvery abdomen will have to do.

The feathery front legs were interesting, too.

I don’t know my spiders as well as insects, so if someone knows what kind of jumping spider it is, I’d love to hear from you.
