This invasive species hasn’t invaded my neighborhood

This is rather interesting: an article from the National Museum of Ireland describing the appearance of the noble false widow (Steatoda nobilis) in that country, in the late 1990s. I haven’t seen any of that specific species in my neighborhood, but apparently they are a significantly invasive species. We have lots of Steatoda and Parasteatoda here, though!

Most of us in Ireland have heard about this recent arrival, but few would know its scientific name, Steatoda nobilis. This spider is more commonly known as the noble false widow.

Interestingly, in an article published at the time (Nolan 1999), Myles Nolan tells the reader that a couple of weeks prior to the aforementioned Bray discovery, another person had found a great number of these spiders on their own property, approximately 250m away from the Bray residence. The author observed at the time that these spiders have a high reproductive rate, and that the spiderlings are inclined to disperse widely from the egg sac, perhaps accounting for this species’ ability to colonise easily.

The Museum specimen detailed in our acquisition register is, however, the first valid Irish record as an identified specimen was lodged with the Museum. That specimen (called a ‘voucher specimen’) is now stored safely in the Museum and is available for study and research.

As Ireland currently houses relatively few animals who pose a risk to human health, this new arachnid is now of great curiosity to the public. The reports, however, are over emphasised, and there is little for humans to fear from the noble false widow.

A recent report from the Irish scientific community however, showed that a common lizard had been preyed upon by this diminutive spider (Dunbar et al. 2018). The young lizard was discovered wrapped in spider webbing, with the noble false widow crouched over its head, presumed to have been feeding on it – a potential worry for Ireland’s only native terrestrial reptile.
The noble false widow can now be found in at least 17 Irish counties, all year round, both indoors and out (although more so the latter). They have a strong tendency to live on manmade structures and materials, such as steel, concrete and timber. Sheds, outhouses and boundary railings provide the perfect habitat for our new arrival.

Part of the reason for the relatively sudden appearance of Steatoda nobilis in the scientific eye, though, is the British tabloids, which had an absolute freakout over big spiders, playing up the nearly non-existent dangers and clutching their pearls over the observation of a few spiders near one of the Queen’s estates. It was ridiculous.

Increase in Spider Recording Scheme records for Steatoda nobilis in Britain parallels intensified
press coverage in the local newspapers (dark blue bars = spider records, light blue line = number of press
articles). The sudden massive increase in records seen in the last decade coincides with the first appearance
of the species in various other countries far from the native range in the Macaronesian islands.

I can vouch for Steatoda‘s eagerness to disperse — when I found the newly emerged clutch of spiderlings yesterday evening, they had nicely spread out equidistant from each other in their container, and when I opened it up, the race was on, with all the spiderlings on the edge of the mass rushing to get out into the larger lab. I think they don’t much care for their brothers and sisters.

The “high reproductive rate”, though, is a relative thing. My impression of Steatoda triangulosa and Steatoda borealis, the local species in the genus, is that they were sluggards compared to Parasteatoda. They take a month to develop from egg to spiderling, compared to Parasteatoda‘s week and a half, and they have much smaller clutch sizes than Parasteatoda. I’ve been sitting here feeling like the Steatodas take forever to get to the point I can work with them.

On the other hand, at the end of that month I am finding myself drowning in baby spiders…

Back from our adventure

We visited Minneapolis-St Paul this past weekend so we could watch Iliana and Skatje walk on Mars…


…and Iliana and Grandma going undersea.

I am reminded that little kids are exhausting. We thoroughly enjoyed our weekend with an energetic 3 year old, but it was necessary to get home to recover. Except…yikes, things are heating up in the lab.

I had one egg sac open up 12 days ago, and another this weekend. A third is imminent — I dread going into the lab today to see even more spiderlings. Then there are two more that will open up in a week. I got home last night and had to sort out and move a cloud of adorable baby spiders into separate containers. I’ve got two small incubators in my lab, and they’ll be full today; I’m running out of the small plastic containers I keep the small ones in. Then I’ve got a Parasteatoda egg sac that is threatening to hatch out any day now.

I am beginning to realize it may be possible to have too many spiders.

Looking forward to seeing stuff from the [PLACEHOLDER] Space Telescope today

This afternoon (2pm PT, 5pm ET) NASA will reveal the first images from their new space telescope. You can see them on their live stream (this is a continuous stream, and you could start watching right now for six hours before you’ll see the expected stunning images).

Now I don’t know what to call the Giant Space Widget. It’s been officially named after an administrator and homophobe, rather than a scientist, and I’d rather not use that name at all. To see why, maybe you could fill some of the time you’re waiting by watching this video:

I’m looking forward to the images, but I’m going to have to refer to it as the [PLACEHOLDER] Space Telescope, unless someone has a better name. Why is it named after a homophobic bureaucrat anyway?

An atheist response…and an invitation to a livestream

I was bored and trawled through a Christian site to address some silly questions.

Hey! Next week I’m planning to do a livestream to talk about Lucy Cooke’s Bitch, an excellent book about biology’s long history of bad science whenever the subject of women comes up, and going through many examples of the complexity of sex in zoology, and also talking about the short shrift women get in science. If you have any interests along those lines, or have read the book, or are, like, a woman who’d like to make sure the man talking about this subject stays in line, send me an email and let me know what times work for you, and maybe we’ll talk.

Let’s hope he isn’t made a martyr to his cause

We shouldn’t forget who Shinzo Abe, good friend of Donald Trump, is.

Two of Abe’s Cabinet appointees were associated with Japan’s Nazi Party and several of his comrades wrote laudatory blurbs for a book called Hitler’s Election Strategy, published in 1994, and written by a member of Abe’s Liberal Democratic Party (LDP). The book was banned after international criticism.

Comparisons with the Nazis are hard to brush off if your Cabinet members are looking up to them as role models.

Let’s not forget that Abe appointed an unrepentant racist, Eriko Yamatani, associated with the internationally condemned Zaitokukai, to oversee the National Police Agency. Neither the prime minister nor any of his senior Cabinet members openly opposed the discrimination against Japan’s Korean residents. Last month, the Cabinet announced in an approved written response to an opposition party’s question on the usage of Hitler’s Mein Kampf as teaching material in classrooms that it was completely acceptable.

After a public outcry, they made the obligatory comment that “if it were used as a tool to promote racism… that would be inappropriate.”

Initially, criticism erupted all over the country but the mainstream media practiced self-censorship and didn’t touch the issue until the outcry forced their hand as well.

Cabinet ministers this year also announced support for reintroducing the kamikaze-inspiring Imperial Rescript on Education back into the classroom. It was issued originally by the Meiji Era emperor in 1890 and advised citizens that the greatest moral good was to give their life for him or his successors. It was later used as part of the ideology that had Japan send soldiers out to die in airplanes as kamikaze pilots, die in small submarines as human torpedoes, and force Okinawans to commit mass suicide. After the war, the edict was declared null and void by Japan’s parliament in 1948, with a statement that it “clearly undermines basic human rights and calls into question Japan’s international fidelity.” Now, it’s on its way back. Indeed, it has been a good year for those nostalgic for prewar Japanese militarism. Bayonet practice will be making a comeback in education as well.

Absolutely none of that justifies murdering Abe, especially since he was out of power. Assassination ought to always be off the table.

Shootings in general are extraordinarily rare in Japan, thanks to their strict gun laws. The assassin here had to construct his own handmade weapon to carry out the evil deed.

Some are more equal than others

This could never happen in America!

Or…could it?

The witches have targeted Brett Kavanaugh, who was just trying to eat his expensive steak dinner, and their protests so disturbed him that he was able to have dessert and had to sneak out the back. Politics should not trample the freedom to congregate and have dinner!

The restaurant announced that Disturbing the dinner of all of our customers was an act of selfishness and void of decency. You know DINNER is not like the privilege of getting respectful treatment at a health clinic, or something.

I’m expecting a decision at the next court session protecting the sacred constitutional right of unelected officials appointed for life to never hear a contrary word ever, followed by a group of unelected christo-fascists with lifetime sinecures deciding that burning at the stake is not a cruel and unusual punishment.

Did UATX increase their status, or did Dawkins diminish his?

I think you know the answer.

This is not a joke.

Somebody really needs to take him aside and explain that he’s making a lot of really bad decisions lately.

Gorillas have very small testicles, you know

Why am I not surprised that Elon Musk sleeps with his employees?

Elon Musk Secretly Fathered Twins With Neuralink Executive, Report Says

Elon Musk had twins in November with Shivon Zilis, an executive at Musk’s company Neuralink, according to court records obtained by Insider on Wednesday, bringing the number of known living children fathered by the world’s richest man to nine.

The twins were born a few weeks before his partner, Grimes, had a child through a surrogate.

Three kids within a month? I’m sure Elon was overwhelmed with his fatherly obligations at that time. Right?

Man, it must be exhausting having to run all these grifting companies AND assert your masculine dominance by fucking your executives, and then having to keep your offspring secret.
