"In-between snacks"
I met this little #Arachnid in the garden, just hanging on a leaf. Was it just my imagination, or did it look at me with hungry eyes (cue in the Eric Carmen song!)?

Photo showing a brownish spider with its legs tucked high on either side if its body, following the contour of the leaf it is perched on. Eyes are black, looking quite intently at the photographer. Mmmmm, photographer... Ok, I'm outta here, enjoy Arachtober, everyone!

Bolas spiders are not easy to find, but I have had the good luck to recently find two. This one had 6 "bolas" hung from the branch that she was suspended from. When she hunts, she emits a pheromone that mimics her moth prey. On approach, she swings the sticky bolas to snare them. #arachtober

A female Bolas spider, Mastophora sp, perched amongst the petioles and buds of a hickory tree. Her legs are folded up tight against her body. The top of her abdomen is adorned with light tan marks akin to some form of alien writing that is reflected symmetrical about her axis of symmetry.

Gossamer threads suspend milky white sticky blobs against a near black background. These are the bolas spider's hunting tools. This one has suspended 6 from a thin branch.

Happy #arachtober everyone. Here is a running crab spider (Philodromidae), from yesterday at the visitor center in Bosque del Apache National Wildlife Refuge, New Mexico, USA. #bugsky #bugwatching #spiders #arachnids

Sprawling, cement-colored spider, facing up, on one of those binocular viewer things. Spider is mottled with darker markings.

Ah, and here's one for #Arachtober! We have a lot of Orbweaver species in Virginia, this one is the Hentz Orbweaver (Neoscona crucifera).

The longer I live the more I appreciate spiders.

I love to host those Writing spiders in my yard. 🌱

#Arachtober 2: checked out the garden wall late last night in the hopes of finding arachnids, found many snout mites (family Bdellidae), including this one feeding on a tiny bristle millipede (family Polyxenidae)!

I have seen very few arthropods preying on […]

[Original post on flipping.rocks]

A bright red mite with pointy mouthparts that are buried in the underside of a small many-legged arthropod covered with little bristles (more of which are scattered around it).

Another angle that better shows the snout mite's elbowed pedipalps on either side of the snout, like a weevil's antennae. One can also see a thick clump of bristles.

Here is what a bristle millipede looks like alive and the right way up, more like a carpet beetle larva or a caterpillar than a typical millipede. Its segments are fringed with rows of bristle-like hairs, and it has two bundles of longer hairs coming out of the end of its butt, a little like the waxy tail of a planthopper.

Happy #Arachtober 2nd and #FlyDayFriday!
I went spider hunting last night and found at least 15 species. And when I got home, I realized this one had caught a fly. I had a very fun Arachtober 1st!

Really nice Cross Orbweaver (Araneus diadematus) sitting in a really big web she built across our barn entrance for #Arachtober

The 2nd of #Arachtober is also #FlyDay.

Sorry about that 🌱

The first of my very limited contributions to #Arachtober, and I am easing you in gently with this Flower Crab Spider, perched near the top of an Orchid flower spike. Photographed at @wtsww.bsky.social Dowrog Common Nature Reserve in Pembrokeshire back in June. #Spiders #Invertebrates #UKWildlife 🌿

I don't have any fresh #Arachtober spider pics since it was raining all day, but here's an old one instead!

It’s #arachtober! Here is a Sylvan jumping spider, Colonus sylvanus, from April.

Mostly black spider with red highlights around eyes and head, white stripes running down edges of body, on a green leaf.

#Arachtober 1: the lights on this pedestrian bridge create giant spider shadows! The casters are the appropriately named bridge spiders, _Larinioides sclopetarius_.

#DailySpiderPic #spiders #orbweavers #Araneae #Araneidae

A pedestrian bridge by night, with downward-facing lights set underneath the wooden railings. A spider has built its web directly beneath one, creating a giant spider shadow on the walkway.

A further-out view showing the bridge curving away, with dozens of similar lights.

An orbweaver spider at the centre of its symmetrical, wheel-like web. It has a darker leaf-like marking (the folium) on the top side of its abdomen which looks a little like a fleur-de-lys.
