Fairy Bees: these tiny bees can measure less than 2mm long, which is smaller than a carpenter bee's eye

Above: two different species of fairy bee

Bees of the genus Perdita, also known as fairy bees, are some of the smallest bees in the world. Their tiny bodies can measure as little as 1.6mm long, which is smaller than the eyes of many bumblebees and carpenter bees.

The smallest species in this genus is the mini fairy bee, Perdita minima, which is so small that it's often mistaken for an ant.

As this book explains:

With almost 640 species, most restricted to the southwestern USA and adjacent parts of Mexico, this genus forms a species swarm of mostly very small ground-nesting bees. One of its species, the aptly named Perdita minima, shares the record for being the smallest bee in the world at just 1/16th of an inch (1.6 millimeters) in length. Unsurprisingly, it favors similarly tiny flowers, such as those of the whitemargin sandmat (Chamaesyce albomarginata).

Fairy bees are solitary, meaning that they don't form colonies or live together in hives. Each female builds her own nest by creating a small tunnel in the ground and then stocking it with pollen.

This article describes the nesting process in greater detail:

Fairy Bees are “mining” bees, referring to the fact that they are ground nesting bees. The females excavate tunnels in the ground somewhere within a short distance of a food source. They then visit flowers, feeding on nectar and collecting pollen on specialized hairs on their legs known as “scopae.”

The females then deliver these pollen bundles to their subterranean nests as a food source for their larva. The larva hatch, consume the pollen bundle, develop through metamorphosis into adult bees and the cycle continues.

Most fairy bees are specialist foragers with very short tongues, so they prefer shallow flowers. They typically fly during the summer and autumn, timing their emergence to coincide with their favorite host plant.

SO CUTE!!!! These ground-nesting bees can be very sensitive to pesticides, even more so than honey bees, which are often used as indicator species for pesticide effects on the ecosystem.

It also goes to show that tiny flowers are just as important as big, showy flowers!

wait, Derin how did your leaving make the hospital shut down?

I used to work as a live-in nanny for a pediatrician.

Now, the thing about hospitals in my country is that they are massively understaffed and massively underfunded. This is especially true outside the major cities. The staff are worked to the bone and receive little to no help in things like finding accommodation or childcare, making working in rural areas a very uninviting prospect; staff come out here, get lumped with the work of three people (because there's nobody else to do it), burn out under the workload and leave, meaning that those remaining have even more work because that person is gone. It's unsustainable and the medical staff are doing their best to sustain it, because people die if they don't, so to the higher-ups it looks like everything's getting done and therefore everything is fine.

My friend (and boss) worked one week on, one week off, swapping out with another pediatrician. This was necessary because it would not be physically possible for one person to handle the workload for longer periods of time. The one single pediatrician had to hold up the entire pediatrics ward, which was not only the only public hospital pediatrics ward in our town, but also the one that served all the towns around us for a few hours' drive in all directions. I regularly saw her go to work sick, aching, tired, or with a debilitating 'I can barely make words or see' level migraine, because if she took a day off, twenty children didn't get healthcare that day, and some of these kids' appointments were scheduled weeks in advance. She'd work long hours in the day and then be called in a couple of times overnight for an hour or two at a time (she was on-call at night too, because somebody had to be), and then go in the next day. Sometimes she would be forced to take a day off because she physically could not stay awake for longer than a few minutes at a time, meaning she couldn't drive to work.

Cue my niece's second birthday coming up in Melbourne. I'd been working for her for about 3 years, and she (and the hospital) had plenty of advance warning that I (and therefore she) needed one (1) Friday off. That's fine, we'll find someone to work that Friday, the hospital said. Right up until the last week where they're like "oh, we can't find a replacement; you can come in, can't you?"

No, she tells them; I don't have anyone to watch my kid that day.

Oh, surely you can hire a babysitter for this one day, they say. Think of the children! We really really need you to work that day. I know we said it'd be fine but we need you now, there's no one else to do it.

There are no other babysitters, she told them. Unless you can find one?

That's not our responsibility, they said.

But I'm not changing my plans, she's got plans by now as well, the hospital knew about this one day weeks in advance, and with absolutely no reserve staff they're forced to reschedule all pediatrics appointments for that Friday. Not a huge deal, it happens on the 'physically too overworked to get out of bed' days too. I go to Melbourne, she goes back to her home in Adelaide for her recovery week, all should be on track.

My niece gives me Covid.

This was way back in the first wave of the pandemic, and there were no Covid vaccines yet. The rules were isolate, mask up, hope. I had Covid in the house, and it would've been madness for my friend and her toddler to come back into the Covid house instead of staying in Adelaide. There was absolutely no way that a pediatrician could live with someone in quarantine due to Covid and go to work in the hospital with sick children every day. And no support existed for finding another babysitter, or temporary accommodation, so the hospital was down a pediatrician.

The other pediatrician wasn't available to do a three-week stint. They were also trapped in Adelaide on their well-earned week off.

Meaning that the only major pediatrics ward within a several-hour radius had no pediatricians. They had to shut down and send all urgent cases to Adelaide for the week. To the complete absence of surprise of any of the doctors or nurses; of course this would happen, this was bound to happen, it presumably keeps happening. But probably to the surprise of the higher-ups. After all, the hospital was doing fine, right? Of course all the staff were complaining of overwork and a lack of resources in every meeting, but they could always be fobbed off with the promise of more help sometime in the future; the work was mostly getting done, so the issue couldn't be too urgent.

It's not like some nanny who doesn't even work for the hospital could go out of town for a weekend for the first time in three years, and get the only public pediatrics ward in the area shut down for a week.

This saga does also illustrate something I learned about in library school, which is: when management starts reducing your staffing (or other resources) to the point that it jeopardizes your ability to function, make visible cuts.

Don't stretch yourselves to the breaking point to keep doing as much as possible, and don't cut corners where customers/clients/patients/patrons won't notice. Say out loud, "Due to low funding/staffing, we can no longer do X," where X is something visible but not mission-critical.

In the library world, this is usually a small reduction in hours: we lose an employee position, we stop being open on Sundays, or we close an hour earlier every day. (And we put up signs saying exactly why, and to whom patrons can complain.)

If you say "this isn't enough resources/we're understaffed/we can't go on like this," but then you continue to go on like this? You've just proved that you can indeed go on like this.

Of course, not everyone is in a position where you can make decisions like this--reducing hours, or suspending a particular service; the reason we learn this in library school is that we usually have a clear bright line between operational management and funding. However, you can still ask. Management says, "For now this store is going to have to get by with 6 employees instead of 7," you say, "Okay; what are we going to stop doing, to make that work?"

And if the answer is, "Nothing," you just...let the problems happen. Someone gets sick, and they really need you to come on your day off? Sorry, but you made plans that you can't break (even if those plans are "lay in bed and eat ice cream"). But they can't open the store if you don't come in? Sounds like the store isn't going to be open. Hopefully we'll be able to get up to full staffing before this problem comes up again!

In the story above, the COVID quarantine situation was, of course, unpredictable, but if management had taken the lesson any of the times when appointments had to be cancelled because a doctor called off due to physical exhaustion, perhaps they would have had some options when both of their pediatricians were unavailable due to a global health emergency; who can say?

It can feel like sort of a dick move--to your immediate boss, your coworkers, your patrons/customers/clients/patients/whoever--to say no when it isn't technically absolutely impossible to say yes. But the doctor and the nanny in this story were both right to stick to their guns about this one well-planned and anticipated day off, and the rest was just a cascade of failure that ultimately stems from the decision to intentionally understaff the hospital, and to ignore warning signs of an impending staffing crisis.

And remember, "we can't find people to hire" almost always means "we're not offering a high enough paycheck".

A Hades and Persephone pencil drawing that I'm going to paint with watercolors :) (or rather, I'm going to print the drawing out on watercolor paper and paint that, so I don't ruin the pencil sketch)

nikkilbook

I’m so excited to see how this turns out! Somehow it hadn’t occurred to me that you could do a rendered under-drawing for watercolor? I thought it would get super smudgy and lose all the detail, and make the watercolor get all cloudy and muddy. The watercolors you’ve posted recent have been GORGEOUS and just as luminous as your digital stuff, so I’m so so excited to see how this one turns out.

juliedillon

It would likely get smudgy if I painted directly over the pencil, but I scan the drawing in, then brighten and tint it, and print it back out onto watercolor paper*. Here's a picture I took of the adjusted drawing printed out onto 140lb hot press paper; I cleaned up a few areas, and tinted the whole thing to be much warmer in tone. So far this has been working out well! I've found the drawing does a good amount of the heavy lifting, which is great because I'm finding I'm enjoying putting the extra time into the drawing instead of jumping straight into paint.

The other benefit of this method is I get to keep the original drawing! And if I mess up the painting I can just print the drawing onto another sheet of paper and start again. :)

*(note: this only works with printers that use pigment based ink, not dye based ink; dye based ink will bleed as it isn't waterproof. I have an Epson Surecolor p800 which has been great, but another artist recently recommended the Epson WorkForce Pro WF-7310 as a much more affordable alternative for printing out drawings for paintings).
