🚨 New Travis McEnery video!! 🚨
The long-awaited sequel to his first video on Agelenidae (hobo spiders, giant house spiders, barn funnel weavers). https://youtu.be/y2LVZhYMtLw
I always learn something new from his videos, and I know a LOT about spiders.
Regularly occurring bouts of retinal movements suggest an REM sleep–like state in jumping spiders
"James O'Hanlon’s Silk and Venom: The Incredible Lives of Spiders is, at heart, a call for us to start telling better spider stories – stories that celebrate the incredible biology of these creatures, rather than focusing on the surprise, terror and disgust they evoke in some people."

Does Portia look more like an ewok or the Lorax? 🤔
Known for their hunting expertise, Portia fimbriata, a.k.a. fringed jumping spiders, are often called the smartest spiders in the world. These tiny #arachnids must be smart and strategic because they eat other species of #spiders, some three times their size, and they even develop specific strategies for hunting different species. 🕷️🐻🧠

If you want to remove a spider from your flat but you're disgusted or slightly scared (very mild #arachnophobia), here's a trick:
1. Give the spider a name (like "Susy" or "Steven").
2. When approaching the spider with the glas jar, talk to it in a soothing voice, using its name, as if calming it down ("now, Susy, it's fine, just a glass jar, you'll be okay").
For me this does actually work.

An unexpected spotting. IDed as a Singapore Frontdoor Tarantula (Phlogiellus inermis), seen resting on a leaf next to the path at one-north Park: Fusionpolis South, Singapore, on 21 Nov 2023. These spiders are usually nocturnal, so seeing one in daylight is unusual.

Do you like spiders?
...okay, even if you freak out when you a big one (I do too), maybe you'd like to KNOW more about them!
Here's a great video by @Plantecarnivore about the Dolomedes Orion subspecies, a big spider that lives and hunt in Japan.
The video (with en&fr subtitles) is full of awesome shots and interesting facts about spiders, so if you're interested you should definitely check it out (and the next ones!) :blobcat_noir:

many years ago, I read a great book on spiders that I found in a library. Sadly I've totally forgotten the title and the author. In one section, it described a serious of experiments designed to determine the minimum number of legs an orb weaver needed to build a web. They showed an orb weaver required 2 legs on one side, and 1 leg on the other side, total of 3 legs, to build a web and catch prey with it, although slowly. Amazing.

Happy Halloween! 🎃👻
Spider berry update, Campanumoea lancifolia:
No ripe berries for Halloween. Alas. I saw spotted cucumber beetle on it yesterday and squished it. Also squished a tree cricket. A couple of unripe berries were slightly nibbled and discarded (probably cricket). I tried a green one and it tastes like baby peas. Not bad. Hopefully ripe berries are better.

Belated #Arachtober 29 because I got vertigo yesterday: missing-sector orbweaver (_Zygiella_) male and female. I think these are _Z. x-notata_? The males wait patiently on the periphery of the females' webs, plucking out little guitar solos. I wish I could have gotten a video for you all, but it was a windy night and everything was too blurry/shaky.
#Arachtober 28: the holes in these wooden posts at Cherry Beach were ideal homes for grass spiders (_Agelenopsis_), which can easily be lured out with a feather attached to an electric toothbrush.
It's always a little sad when I put the toothbrush away for the season. Over the next few months, I'll mostly be finding spiders by flipping rocks and fallen bark and turning over pine cones. Anyone else got winter spidering strategies?
There is evidence to suggest that spiders are declining worldwide. But for most species, we don't really know, because data and funding for spider population studies is badly lacking.
Everyone with a phone camera can help. See a spider, get a photo, add it to iNaturalist.

This beauty has taken up residence on the lid of one of my plastic bins. You're more than welcome. I only ask to not jump on me when I open the lid, and I will try to remember to open it slowly.

Our collective arachnid aversion could be causing us to overlook something even scarier: Spiders may be disappearing.
By Betsy Mason 10.25.2023
"In fact, all over the world, all sorts of spiders seem to be disappearing, says conservation biologist Pedro Cardoso of the University of Lisbon. He and a colleague polled a hundred spider experts and enthusiasts globally about the threats facing the animals. 'It’s more or less unanimous that something is happening,' he says.
"The case for why people should care about spiders is robust. First, the vast majority of spiders do not bite or harm people, despite rampant misinformation in the media that would have you believe most spiders are out to get you. In reality, a vanishingly small number of spiders are dangerous to humans. Instead, they prey on insects — including mosquitoes, cockroaches and aphids — that actually do cause harm to people in their homes, gardens and fields. Spiders are excellent natural pest controls, but they are often killed by pesticides aimed at those same insect pests. These #ToxicChemicals also harm people.
"Spiders are important food sources for birds, fish, lizards and small mammals. And there are untapped benefits we humans could enjoy someday — if spiders don’t disappear first — such as potential pharmaceutical and pest control applications derived from compounds in their venom, and medical and engineering applications based on their incredibly strong silk."
#Arachtober 24: a juvenile male _Hypselistes florens_, a very charming and unusually colourful erigonine. Not to be confused with the similarly named (and similar-looking!) orbweaver _Hypsosinga_.

Hello you lovelies! To have something touchable to show off in bologna, and not only a digital folio, I made this "counting to 10"- leporello. It has bats, spiders and pumpkins in it. Here's a little sneak preview. Have a spooky autumn weekend <3

#Arachtober 14: A wasp's progress. Over a few weeks in July, I saw a cobweb spider on a fire hydrant parasitized by a wasp larva, then the wasp's pupal cocoon, then at last the empty cocoon.
Some parasitoid* wasps alter the spider's behaviour to make them spin a web more suited to sheltering the pupating larva; not sure if this was the case here.
There are also hyperparasitoids that target parasitoids, so for all I know the wasp itself may have been parasitized and a different species emerged!

* "Parasitoid" means a type of parasite that eventually kills its host rather than simply feeding on it. Your typical parasitoid is a solitary wasp that lays eggs on hosts which become larvae that devour the host, often from within.
#Arachtober 13 (it's still the 13th somewhere!): a fast-moving, red running crab spider (family Philodromidae) eating an equally fast-moving, red whirligig mite (family Anystidae)! From back in July, seen on the Park Dr Reservation Trail, southwest of the Evergreen Brick Works.
Possibly _Philodromus rufus_? I've only identified a _Philodromus_ to species like, once.

For #arachtober I repost this wolf spider found on the wall of the house this summer.
Started cleaning its legs when I took the photo and then it run away. The body was nearly 2cm long.

#Arachtober 10: from back in June, a mesh-web weaver (family Dictynidae) back-combing a line of silk to turn it into a fuzz of nanofibres. Spiders like this have a special sieve-like silk-making organ called a cribellum. This in fact is the ancestral state of most spiders.
Cribellate silk doesn't use glue; rather, it melds with the waxy compounds on some insect exoskeletons. It doesn't stick very well to other surfaces. Later in spider evolution, spiders developed other types of silk that could catch different insects and support more ambitious aerial webs. However, for a minority of spiders, cribellate silk still works just fine.
More details in this 2017 paper: https://royalsocietypublishing.org/doi/10.1098/rspb.2017.0363 :OpenAccess:

#Arachtober 8: a hacklemesh weaver (_Amaurobius ferox_) emerges from its lair in a seriously grimy underpass.
This family of spiders is very closely related to the Agelenidae—there are many species that have moved from one to the other and vice versa over the years—but they are (generally?) cribellate, that is, they make a kind of fuzzy silk.

#Arachtober 6: on a Queen Anne's Lace umbel, a crab spider (_Mecaphesa_?) has caught what looks like an ant alate.
For today's #arachtober: a brief story. I was finding Colonus hesperus spiders seeming to rest at night while dangling from a short silk thread. Thanks to #scicomm Twitter, I found a very recent study on exactly this behavior in a different jumping spider species. Because the internet is neat, I was able to contact that scientist and add C. hesperus to the list of dangling resting spiders.
