SPIDERDAY is finally back - it’s been a few weeks, but the end of the term has been hectic. However, it’s time to catch up on some great Arachnid-themed links from the last little while.

This will also be my last post of 2015, so I’ll also take this opportunity to THANK YOU for reading and commenting on this blog. I also wish everyone a Happy Holidays! Arthropod Ecology will certainly keep on truckin’ in 2016.

Here’s looking at you… A close up of an Araneidae, from Insects Unlocked.

Here’s a post on an often-overlooked family of spiders: The Oecobiidae, aka “star-legged spiders”

Spiderday (#17)

September 19, 2015September 19, 2015 / Chris Buddle

Arachnids: cool, amazing animals with lots of legs and lots of fascinating biology. SPIDERDAY brings you the best arachnid links from the past week. Here’s your 17th edition:

A wonderful shot of a crab spider: part of the brilliant “insects unlocked” project.

Arachnologists in some parts of the world are getting LOTS of questions about all the spiders showing up in houses, on buildings and just about everywhere. This happens every year around this time, ’cause it is autumn. Here’s a great summary of this (and my Read of The Week)
One very common species that people are noticing this time of year (at least in my neck of the woods) is Neoscona crucifera, and this post provides a great summary of the species.
Under the heading of “ridiculous“, there’s a company selling spider-proof sheds. Spoiler: don’t waste your money.
Wasps that turn spiders into the walking dead. Boom. (here’s another write up of the story)
Here’s a really wonderful blog about orb-weavers called ‘thorned heart’. It includes taxonomy, natural history and photographs.
They are finding some lovely spiders in Australia… Hello there indeed!
For the taxonomically inclined.. new species… more than that.. new Genus of spiders from southern Africa.
Spider love. Yeah, for the jumpers.
Oh dear: spider scare causes school bus crash.
Mitey Mites grabbing a ride: in this case, new species on beetles.
Want to kill dust mites? Stop making your bed. Well… it’s not that simple, but that is quite a headline!
Love the enthusiasm for spider silk in this video. SUPER STRONG SPIDER SILK YEAH!

Spiderday (#13)

August 22, 2015August 22, 2015 / Chris Buddle / 1 Comment

After a busy summer, and a lot of time away, I’m pleased to start up Spiderday again. Here are some arachnid-themed links pulled from the web over the past couple of weeks.

Here’s a nice looking spider - it’s a Selenops. There is exciting new research about these critters! (photo by Sean McCann)

The photo, above, provides a segue to my read of the week: some species of neotropical spiders don’t just ‘fall’ from trees, they can ‘glide’ and use their flat bodies as a type of sail to redirect them to the tree trunks. Wow…. just WOW. Here’s one take on this story, and here’s the original paper.
Nice spiders finish last - and determine the fate of the colony. Some really neat research about colonial spiders.
Tooting my own horn here: I was thrilled to see quite a lot of interest about our research on the effects of insecticides on jumping spider personalities.
Here is a Festschrift of interest: The life and times of Africa’s First Lady of Arachnology, Ansie Dippenaar-Schoeman.
Male wolf spiders do some eavesdropping.
Another tiny dancer (peacock spiders…. of course!)
If you don’t follow the Biodiversity Heritage Library, you really should. Case in point:

An important statement about tick-borne diseases, put out by the Entomological Society of America.
More about Lyme - here is a post about some important new research on how/why the disease symptoms vary so much, and treatment implications.
On varroa mites, honey bees, and pesticides. It’s complicated.
Confusion in the world of Arachnology: Opiliones (harvestmen) or Mite? (Acari)????
Bioindicators with eight legs: water mites can help inform us about water quality (oh, insects can do that too)
Tooting my own horn again: It was so wonderful that CBC science & technology picked up my story about pseudoscorpions and wrote a nice piece on these animals. Curiosity, passion and arachnology FTW.
Here’s a wonderful video about arthropods of homes, in Peru. It’s here because there is loads of great spider coverage:

I’m delighted to bring you the twelfth instalment of SPIDERDAY! All your arachnid links, at your fingertips!

Please note: I’m going to be away (vacation time…) for part of August - your next Spiderday will likely be on 22 August. Hope you can wait that long!

From Jonathan Kolby, an awesome net-casting spider! Amazing animals.

Green Lynx Spiders - friend or foe? My Read of the Week.
A moth that mimics a jumping spider. And if you don’t believe the photo, there’s a paper about it too.

Boom: new spider species (in Kerala). Always good news.
Wolf spider cannibalism? Yes, it’s important.
Spider of the Dominican Republic: there’s a blog for that.
Here’s a very interesting post that is all about how wasps take down spiders: spiders are prey too!
Here’s a video on that topic:

in New Zealand, here’s a post about mites that may prove to be important biological control agents against wasps. Mite-y powerful!
On damselflies and mites: Regionally widespread parasitic water mites have relatively broad host species ranges. Nifty paper!
An unlucky Opiliones:

Spiderday (the ninth)

June 27, 2015June 27, 2015 / Chris Buddle / 1 Comment

Here’s your ninth edition of SPIDERDAY! Some arachnid-related links from the past week.

Please note: I’m just heaving off to the Yukon for a couple of weeks of remote field work (it will involve arachnids!). Spiderday will likely return on 18 July.

Wow - this is a Thomisidae (crab spider) that’s an ant-mimic. In Australia, of course. Photo by Alex Wild.

“An estimated 25,000 diving tarantulas live along a 10 kilometre stretch of floodplain“. Australia - you have the best arachnids. Honestly. This is my read of the week.
Always good news when new spider species are described: here are ten new species from Madagascar. In this work, the authors document ‘remarkable’ local diversity within the genus Anelosimus.
Cuff links, spider style. Nice.
The American Arachnological Society had its meeting last week: you can check out some tweets to gets a sense of the conference.
Click here to read about a remarkable overreaction to finding a spider in bananas. Sigh.
You just don’t hear about these critters very often: The formidable “jaws” of the solifugae (camel spiders, or wind scorpions). Not convinced…? Here you go:

The “Big Bad Spider“: a wonderful post about why spiders might so often be featured (in art, books, culture) as monsters and villains.
A spider’s egg sac does not always produce spiders.
Always great to see more species of spiders described: in this case, some arachnids from Australia, including lovely Mygalomorphs.
More on mygalomophs: this paper shows a radiation of cryptic, endemic species in California.
