Great summary, thanks!

Despite the great images of IO the linked article comes with this mud pearl "[University of Arizona's Large Binocular Telescope] With two primary mirrors measuring 8.4 m (~27.5 ft), it has a collecting area slightly greater than that of a 30-meter (98.4 ft) telescope."

according to Science in Poland.

A cross from the 15th century.

Was Poland not widely Christian by that time?

Can you help me id this larvae by Francisco in c/bugs@lemmy.world

Thanks! Seems like handpicking the larvae on the first generation was not thorough enough. Now it's a horde. Today it's looking bleak for one of the 4 plants ':)

The consumption of leaves is astonishing.

On the positive, this has been a good science project for my 5 yo. Catching larvae and pupae, and watching the birthing moth.

We're not eating tomatoes (from these house plants anyway) but we're having some fun.

That Regal moth is awesome! The caterpillar too. And I think i'd surrender the tomatoe plants to them the first time I saw them around.

I believe now this is a Tomato Looper, aka Golden Twin-spot moth

Chrysodeixis chalcites.

From a 12yo reddit post with a very very similar larvae on tomato plants, somebody said it was a cabbage looper (wiki).

But after chancing a search for "tomato looper" I finally found a different species with a very very similar larvae and from there a name and good photo for the moth, Golden Twin-spot.

Now to find how to save the plants!..

Would be lovely, but the butterfly/moth is quite a bit less colourful.

If I let them grow, I'm sure I can send you a good bag. XD

Google searches point to that one alone. And the photos do not suggest a lot of shape variability.

But I'm not convinced because the ones I have (1) do not grow a 'horn', (2) the Nr of legs don't seem to match: also they don't grow as chubby and no line markings.

Strongly on favour of your suggestion.. the larvae my tomato plant has, they do glow under UV light.

Found it on my tomato plant. I'd seen them before in sizes up to 4-5 cm. They eat the tomato leaves like crazy. And (naturally) poo a lot. Some black granade like aggregates. Once grown they molt into a moth that I saw a few days ago. And now my tomato plants are again riddled with these buggers.

This photo was done with the help of a stereoscope. The grid squares are 4mm inside, and 5mm outside the lines. So this juvenile has about 1cm.

I'd love to ID them. Any advise on how to control them without pesticides is also welcome.

Found it on my son's hair after a 10min visit to our veggies garden. My guess is that it might be a tick but we are not in an area of lime disease and although it's an open, rather unkept, field the only mammals I see around are 2-3 stray(?) cats.

The photo was done using a stereoscope+smartphone. The dark lines underneath are .4 to .5 mm.

Any pointers would be welcome.

You feel free to use expressions and terms as "rub me the wrong way", "buzzwords", and "clickbait". In those cases you are okay with the listener/reader interpreting the implicit meaning over their explicit wording. Why is "forever chemicals" different? Specially in an informal communication setting.
