Hey, Fedi. I have a favour to ask you.

[statsguy@mas.to]

@annehargreaves @ShaulaEvans Yes they are! Sadly I don't have a photo of any.

@ShaulaEvans here's one I learned yesterday: earwigs are harmless creatures, and they have beautiful wings that fold in super tiny elytra. When they unfold they look like they belong to some kind of unreal cristal butterfly.

@ShaulaEvans Male bees (and wasps, and ants) are _haploid_ and do not have fathers. They are not just the only animals, but the only _eukaryotes_ to evolve reproduction that differs from the normal alternation of haploid/diploid generations. (Reproduction is usually very strongly evolutionarily conserved, for obvious reasons: if a mutation messes it up somehow, there's no chance for it to get sorted out again in future generations, because there won't _be_ any future generations.) So euphemising sex ed as "the birds and the bees" is unhelpful, as "the bees" are literally _the_ worst available model organism for human reproduction.

@ShaulaEvans okay, here are some fun/gross/terrifying bug facts about polycheate worms (which live in the ocean):

1. The Bobbitt Worm is a marine ambush predator that burrows in ocean sediment and then shoots out to grab prey with its mandibles, the force of which sometimes cuts prey in half. It grows up to 3 meters long in extreme cases, although it's only about 25 millimeters in diameter. At least one article I read mentioned toxic bristles, but I wasn't able to find a legitimate source for that and suspect it was sensationalization.

2. The Bearded Fireworm does have toxic bristles (as do other fireworms). They can cause a painful sting that lasts for hours. They're also quite beautiful.

3. The Palolo Worm spawns by growing tail segments filled with sperm or eggs, and then on a specific night tied to the lunar & solar cycles, releasing these segments to float to the surface, where they disintegrate into a frothy mass. They're apparently delicious fried in coconut oil.

@AnAutieAtUni @ShaulaEvans As it happens, I was pointing to a tiny, delicate green-and-white jumping spider (most likely Epeus sp.) on a wooden railing just a few hours ago, and before I finished saying "look at this spider", it had hopped up on my finger, cool as you like. And after several seconds, I tapped lightly on the railing, and it hopped off again. Lovely.

@ShaulaEvans

the cockchafer and the red-headed cockchafer exist

[mudlark@bark.lgbt]

@ShaulaEvans oh, oh I have two:

isopods are one of my favourite creatures, but I can’t tell you about them because they’re not bugs - they’re actually crustaceans!

Jumping spiders are the only spiders that can look without turning their heads, but unlike most eyes which look left and right and the retinas stay put, the jumping spider has fixed eye lenses, while the retinas move around behind them!

@ghouston @jetlagjen @ShaulaEvans yes they can! https://simonleather.wordpress.com/2013/03/19/living-inside-your-grandmother-the-wonderful-world-of-aphids/

@AnAutieAtUni @ShaulaEvans Oh, and this is a jumping spider too. It might not exactly be a "fun fact", but still…

@afewbugs @ghouston @ShaulaEvans they really are amazing little things!

Ants farm them on some of my fruit bushes, so at the right time of year I get to see babies, adults, and winged adults up close. It's fascinating to watch how the ants care for their herd.

@ShaulaEvans The first computer bug was an actual bug

@ShaulaEvans I mostly love other kinds of animals, but this one is really interesting for me as a mathematician 🙂

@ShaulaEvans Another bug related fact is New Zealand's competition to be elected as #NZBugOfTheYear!

Voting is done online so probably determined by humans but I guess New Zealand Entomological Society are open to any votes that meet their criteria.

@ShaulaEvans BUG FACT: at least a few times a year I see a cool beetle, go "wow!!! Cool beetle!!!", grab it and let it walk all over my hands and arms for several minutes, and then realize I forgot what blister beetles look like yet again

[biobaum@bildung.social]

@ShaulaEvans
Some leaf beetles produce toxins which they can secrete through glands on their back.

...other leaf beetles feed on poisonous plants, "collect" the toxins and secrete them (sometimes chemically modified).

... and *some* leaf beetle larvae keep the toxins of the plants inside their digestive tract making their feces toxic. Their anus is at a position where they shit on their own back producing a protective "fecal mask". No shit.

@StevenLawsonPhotography @ShaulaEvans Male scorpion flies offer a piece of prey (smaller insects) to the females. The females feed on it while mating takes place.

@emmadavidson @ShaulaEvans oh wow we also have a blue butterfly symbiotic with ants in the UK! It never occurred to me that this sort of relationship could be happening with species across the world! https://www.dorsetbutterflies.com/species/chalkhill-blue/
