Crab spiders get their name from their widely-splayed and elongated first two pairs of legs, which they use to catch prey bigger than they are. They do not build webs but wander around and hunt, often in flowers. Wrestling with prey several times their size can damage the spider — this one is missing a…

Twin Flagged Jumping Spider
Wikipedia wants to tell me that the twin-flagged jumping spider’s name comes from those white marks on its cephalothorax, but I’d put my money on the name coming from those bright white pedipalps, which look like little flags waving around as she moves. This glorious little twin flagged jumping spider, Anasaitis canosa, is almost invisible…
Pantropical Jumping Spider
I assumed at first this was a wolf spider, Lycosidae sp. I am hesitant to call it a jumping spider because this individual was “huge” — I would have put it at half an inch long — and pantropical jumping spiders seem to max out at 12mm with the females. On the other hand, half…
Gray Wall Jumper
I glanced to my side while walking and happened to notice this minuscule little lady hanging out on the pier at Wilderness Lodge at Walt Disney World — so she might actually be a clever animatronic spider. Gray wall jumper spiders (Menemerus bivittatus) are actually human imports to Florida, but fortunately they’re one of the…
Crowned Hentzia Jumping Spider
Probably an almost adult male, and all of 3mm long, this Hentzia jumping spider (Hentzia mitrata) was virtually invisible except when it moved. (Fully adult males are not spotted, like this one, and have larger and furrier chelicerae. There is a theory that resembling a female while it’s a juvenile can help protect a young…
Cobweb Spider
This little lady (about 5mm long) is a cobweb spider (Theridiidae sp., possibly Theridion varians, although the geographic range is wrong for that). She lives on my garage door, and I’ve photographed her a couple times “posing” with that Asian tramp snail (Bradybaena similaris) shell. This morning she had produced a beautiful egg sac of…
Hentz Orb-Weaver
This immense nope of a spider, about two inches in diameter and very peeved to be disturbed, was encountered strung, at face-height, across a walking path at the Oakland Nature Preserve in Florida. I originally abandoned Neoscona crucifera (the Hentz orb-weaver) as a possible identification, since Wikipedia says they only get to be an inch…
Wall Spider
I needed help with this one (thank you, /r/spiders!). At 2.5mm long, there weren’t a lot of details to go on! This petite lady is an adult female wall spider (Oecobius navus, very probably), and isn’t she darling? She’s sitting on my pillowcase, to give you a sense of scale. Other than being tiny and…
Magnolia Green Jumping Spider
The Magnolia green jumping spider (Lyssomanes viridis) — this individual is an adult male, with fantastically elongated chelicerae that you simply cannot see without macro photography. Compared to the more sedate, round females, this handsome boy looks almost like an alien being. I love this species’ little red “hat”! Lyssomanes are one of the more…
Trashline Orb Weaver Spider
The name of the trashline orb weaver spider (Cyclosa turbinata) is derived from the thick vertical line of silk and/or debris in its web. Called the stabilimentum, the line may help stabilize the web, may attract insects, or may deter birds from flying through the web by making it visible. The line of silk also…
Banana Spider
Huge but harmless, this lovely lady is about four inches across. A male of the species is only about 1/4 her size. These spiders are commonly called “banana spiders” not so much because they are yellow, but because they are often found among bunches of bananas during harvesting. I originally found this species described as…
