Greedy, part Three (procrastination edition)

I'm still sorting forgotten photos.

First, the backstory: In September of 2018, I was suffering a plague of fruit flies, come to feast on the apples in my yard. A pretty cross spider had set up her web in a doorway, and I was happy to leave her there; she was helping out with the fruit flies. I named her Patience, because she sat there for days without moving.

I posted her photo at the end of August; she had caught one fly, tied it up, and gone for the second, which she hauled back and tied up with the first before she settled down to eat.

A week later, she caught 6 flies and tied them all up in one bundle.

Then I was busy; school had started, and I had time to take her photo again, but no time to process them. They've been sitting on my hard drive ever since.

So here's the next in the series:

Patience, with a humongous, densely packed ball of fruit flies.

She had abandoned her web in the doorway and moved down, closer to the bowl of apples on my table.

Hauling them off to a corner to eat them.

She's called a cross spider because of the pattern towards the front (bottom here), but she could also be a pagoda spider by the rest of the art. In Latin, she's Araneus diadematus: a crown spider.

Sigo revisando fotos olvidadas.

Primero; la historia. Hace año y medio, en septiembre de 2018, sufría de una plaga de moscas de fruta, porque los manzanos alrededor de mi casa estaban llenos de fruta. Una araña bonita "diadematus" se había instalado en una esquina, con mi aprobación porque ayudaba con el control de las moscas. Le puse el nombre de "Paciencia" porque ahí esperaba, dia tras dia, sin moverse.

Al final de Agosto, le saqué unas fotos: había cazado una mosca, la había atado, y luego fue a cazar la segunda, la cual trajo a amarrar con la primera antes de sentarse a comer.

Una semana más tarde, capturó 6 mosquitas, y las amarró todas juntas en una bola.

Después, yo estaba ocupada; había empezado el año escolar, y aunque saqué unas fotos, no tuve tiempo de procesarlas, y allí han estado olvidadas en la computadora hasta ahora.

Bueno, aquí están, for fin:

Había abandonado su red en la esquina, y se mudó más cerca al plato de manzanas en mi mesa. La encontré con una pelota enorme de muchas moscas de fruta.

La última foto muestra el diseño de su abdomen. Se llama, en inglés, una araña de la cruz, por las marcas hacia el frente (parte de abajo de la foto). Pero también se le podría llamar una araña de la pagoda china, por el diseño completo. En Latín, se le llama Araneus diadematus, o sea, araña de la corona.

Greedy!

The apples on the tree outside my bedroom window are ripe and dropping on the ground. I've collected several bowlfuls for eating, made a batch of applesauce, and baked a few with oatmeal crumbles. The compost bin is full of apple cores, and the house is full of fruit flies.

I've trapped many, but there are always more. And now my corners are full of tiny spiders getting fat on fruit flies. I appreciate their help.

Fruit fly on the kitchen wall.

A few of the apples, with the few fruit flies that didn't leave when I approached.

Fruit flies on a blemish on an apple.

A small cross spider, Araneus diadematus, has built herself a web in a handy location (for me) just at eye level by the kitchen entrance, and seems to be a bit bigger every day. I caught her two days ago with a mouthful of fruit fly:

She's so handy I can even measure her without disturbing her. She's 7 mm long today.

 I've set up a fruit fly trap, which did reduce the airborne population a bit, but then I decided to feed my friendly cross spider. I took off the lid an inch away from her web, and two fruit flies hit the web immediately. Instantly, half a second or less later, Little Miss Patience, here, had dashed across the web and caught one of the flies. As expected.

What surprised me was that now, with her fangs full of fruit fly, she dashed to the other end of the web and grabbed the second fly, then returned to the centre carrying both of them. Which she tied up in one little bundle and settled down to eat.

A veritable feast; a two-fruit-fly taco!

When I came back a few hours later, there was no sign of the flies. The web was clean and repaired, and LMP was sitting in the centre, waiting again.

And the rest of the flies from my trap were loose; they're even perching on my computer screen as I work.

I wonder; if I gave her three flies, would she catch all three together?
