Hey-lolly-golly, get it any way you can!

This is especially for Darina, because she can’t believe my moths are SO KINKY.

These are both males.

They’re hooked together really well.

This little grouping is one male, mated with a female – and then another male who has hooked up his claspers on the other male’s wing. I can’t imagine that would be comfortable.

But, once again… you can see that they’re firmly attached. Imagine supporting your entire weight by your prehensile penis, and you can get an idea what’s going on.

These two males must have timed it just right, because they usually can’t hook up with a female without a fairly clean mating of the genitalia. I’m not sure if one, both, or neither was actually hooked up enough to get the job done.

Trimoulters

I am raising a Thai strain of silkworms.  This spring, I had one good-sized group, and they all made moderately sized cocoons – except for one, which turned out tiny.  The summer group, I will admit, got a little bit neglected; I moved during the middle of their cycle, and  so they sometimes got not enough food, or old leaves because I couldn’t find the new ones near my new house… you get the idea.  Poor little red-headed step-child worms.

So – some of them decided that life was tough, and they would cocoon early.  They spun up in the fourth instar, making TINY but perfectly-shaped cocoons.  My friend Eika explained that these are called trimoulters, and they are typically caused by feeding over-matured leaves.

Now – these are a naturally small strain.  Chihuahua puppies are never going to grow up to be German shepherds – but the trimoulters are *freakishly* small.  Here’s a comparison of normal Thai cocoons, hybrid Chinese cocoons, and the trimoulters.

and here’s a comparison of the normal (smallish) Thai pupa, and the trimoulter pupa

And, in a move that should surprise no-one, they hatch out as freakishly small moths.  They’re SO CUTE.  Like pinchums-widdle-cheekses cute.

Despite being tiny, they are breeding vigorously.  I’m curious to see what will come of it – and whether the eggs will be visible.

Fiddlebacks

I haven’t been writing much lately, but a LOT has been happening.  Chris and I moved house, I’ve written an article, getting ready to film a presentation for a museum – I really need to write it all up, but not tonight.

Tonight, I’m stuck with spiders.  In the past couple of weeks, we have found five brown recluse, or fiddleback, spiders, in the house.  They’re not aggressive, or dramatic – but they push my buttons.  For some reason, I can hold bees in my hands and let them lick the honey off, but these *particular* spiders freak me right out.

My grandmother was bitten by one many years ago.  I was probably ten or eleven at the time, maybe a little older.  She got a necrotizing wound on her forehead which required daily medication for many months, and eventually plastic surgery to replace a void in the flesh.

If I didn’t have several hundred silkworms currently chomping away, and a video to shoot for a major museum in two weeks, I would probably go get some heavy-duty spray and “nuke ‘em ’til they glow so you can shoot ‘em in the dark.”   I’m usually more of an Integrated Pest Management type, slow and careful with chemicals – but there’s something about these particular pests.  I’ve ordered glue traps, and will start out with those and see if I need to move up to wettable powder around the baseboards.

One thing that they don’t mention in the literature (that I have found, at least) is that if a recluse is hiding out beneath the treadles of your loom, and you bump the loom with the vacuum, it will run out and bounce up and down on the carpet.  I don’t know whether it’s a threat posture, or if it was just freaking out from the vibration – but it’s not what I’d call reassuring.

Any of my Japanese-reading friends on mixi.jp?

I know that several people on my friends list read, or are learning, Japanese – is anybody on mixi.jp? I’m getting website hits from there, and I’m curious what they’re saying, but I can’t even read the page where it says you have to setup a login!

More on the sewing thread

The Lendrum has made it SO MUCH EASIER to produce sewing thread. This is a three-ply tightly twisted organzine. I’m using three filaments per ply, and it’s making up to about the weight of Size C from Belding Corticelli; I hope to be able to make some Size A as well, for finer weaving.

This is the three ply, approximately 20 twists per inch each way.

Because the raw silk is stiff, the skein stands upright, like a stick.

The silk, boiled off. Yes, I used this picture earlier.

Laid across a spool of Belding Corticelli Size C sewing silk. I want to make Size A, too – but I may end up having to adjust the filament size to get there. We’ll see what a 2×3 looks like!

Thread Counter

I found this item on Ebay a while back, and have been finding more and more of its information.  This photo isn’t of the individual piece that I got (it’s from another site that had one on offer) but it’s identical.

from the seller’s description:

“Thread Counter Micrometer for Cotton, Linen, Silk and other Textile and Fabric. This brass and steel precision instrument measures the density of woven and knitted fabrics as well as wire meshes. Made in 1910 by E. V. Cook & Co. in Manchester with 5 graduated scales on rotating silver rules as follows: 1. Inch scale divided into quarters. 2. Inch scale divided into ten parts. 3. Linen measure (L). 4. French millimeter (mm). 5. French Ligne (F), a traditional unit of distance in French speaking countries, equal to 1/12 French inch (pouce). The magnifying lens ocular (X15) can be easily adjusted. The instrument comes with a leaflet with operating instruction and a box (size: 10X8X7.5 cm) lined with purple velvet.”

I’m looking forward to using this for counting the twists in tiny threads.

More happy bobbins

I found out that I can do this in the course of a (longish) evening:

That’s a bobbin full of four-strand tram.  I can do the tram much faster, because it’s twisted about five times per inch, instead of 20.  This is going to be a soft, shiny yarn for embroidery.

It’s cool that you can see the difference in twist just from the sheen… the shiny one on top is the tram, five twists per inch; the one on the bottom is three-strand singles for organzine, at 20 twists per inch.

Happiness is a Full Bobbin

Originally published at WormSpit. You can comment here or there.

That’s an ounce and a half of three-ply organzine singles… tightly twisted from three filaments, about 20 twists per inch.  I’m curious to see what I end up with, length-wise; mathematically, it ought to be about three thousand yards.  With the high speed wheel, it has only taken me a few evenings of twisting.
