The outside (or ‘edge’) of the occlupanid is often smooth, but many species sport palps, or tabs. These have unguessable purposes for mating, locomotion, defense, take your pick.

I propose that these palps or tabs are remnants of the reproductive cycle, vestigial points of contact in the budding process. This phenomenon can be observed in some other classes within phylum Plasticae, and I see no reason to assume it is not happening here.

The gunpla family has especially prominent ones, apparently used in mating displays.

This is where the morphological approach falls down. This is an "analogous trait", i.e. something that's arrived at through two independent evolutionary pathways.

These palps are due to a reproduction process called "stamping". Sounds violent, but that's nature for you. This is an asexual process. The tabs give an advantage to the overall clutch of young, not individuals.

There's a morphologically similar trait in other Plasticae that's the result of "injection moulding". This involves the mating of two (or sometimes more) parents. This method allows for the evolution of more complex features.

Overmoulding is also possible, which produces symbiotic organisms.

please tell us about potential competition between Occlupanida sp. , and members of the Torqueroligiverasacculum Genera [least spotted twist tie]

In my experience, in natural environments that contain a vertical paper towel holder, Torqueroligiverasacculum Genera finds a nest and potential mating area underneath.

But why

stogot• 1 month ago

At first , by the title, I thought there were parasites growing on these clips. Anyone else?

loloquwowndueo• 1 month ago

Same here heh

BretonForearm• 1 month ago

It's the only correct take, since the title atop literally says "parasitoids on bread bag tags".

Terr_3• 1 month ago

Hmm, if we're being really pedantic and go a step further, it becomes incorrect take: The text says parasitoids, which resemble parasites but probably aren't.

Much like how "asteroid samples" means rocks instead of hot plasma from stars (aster), or "android battery" doesn't mean something surgically cut out of an human man (andros).

The link is neat, but that would have been much cooler IMO.

ccamrobertson• 1 month ago

Yes, same. I am now really curious for someone to culture bread tags, milk tops and fruit stickers.

conductr2• 1 month ago

Same initial thought. Took me a solid 10 seconds for orient myself, not usually finding HN as a source of comedy so my context was polluted

Must be one of the most submitted pages. Is there a list?

I distinctly remember seeing an exhibition of this work in Los Angeles in the early aughts. For the life of me I can't remember where. The photos were shot with a macro lens and blown up so that each specimen was ... 12" square? maybe bigger?

Even then there were dozens upon dozens of them on display. It was mind bending.

If you're into this sort of thing I can highly recommend the parasite museum in Tokyo https://www.kiseichu.org/e-top

When I was a child, I remember going to the nearby children's museum and seeing an exhibit with 1 million bread tags. It was supposed to help conceptualize the number.

I've been getting listicle spam/ads with a CTA promising to reveal why you should always carry one of these in your wallet. To this day I never found out why that is!

In Australia they are occasionally used as a temporary fix for plastic sandals when the piece between your toes pulls through the base you can push it back through attach one of these around it on the bottom and it will hold long enough for you to get new ones.

And for a cheeky example, here's a jandal you can buy with the plugger + bread tag combo from the factory

Pretty sure “fusoridae” had a prominent role in the original Tron movie.

This is the work of a mad genus.

It took me quite a while to figure out what the article is about. These don’t seem to exist over here.

junon• 1 month ago

They're the American (perhaps other places) equivalent of the little wire ties, almost exclusively used for bread. They're supposed to be quick to close the bread bag back up but in my experience they're I'll equipped for that purpose as they either break or maul the plastic.

I thought they were commonplace until I moved outside the US; at least here in Germany I never see them.

As kids you'd break off one of the half-circle parts, stick it on your finger and flick it to make a makeshift ninja star.

I consider them a disposable freshness seal. After opening a new bag, I toss it out and just spin the bag real tight and tuck it under. The weight of the bread holds the twist.

It’s super effective but my wife isn’t a fan. Neither was my mom.

These used to be absolutely commonplace in the UK with Sunblest in particular, but also supermarket-baked bread, when I was a kid and then they largely disappeared. I haven’t seen one in maybe twenty five years, probably more, but I gather they have crept back into use in places.

Bread bags are pinched and taped, folded and over and taped, or (in the case of supermarket-baked bread) maybe taped paper if not actually simply folded.

Bread in the UK has improved so enormously in my lifetime that we have largely abandoned sci-fi long-life bread anyway, though Sunblest is still around for any quiet men the kids have given cheeky nicknames who are still saving up for a boat. We’ve also largely moved away from giant loaves of bread towards smaller loaves, but the bigger stuff increasingly seems to be sold in waxed paper anyway.

So reusable sealing devices just seem silly.

They're also used where I am with milk to keep the outer bag closed.

vintagedave• 1 month ago

Perhaps the species hasn't spread to your area of the world yet - where are you?

I'm familiar with them from Australia, where Orthogonidectes seems the most common, and was a helpful addition to our bread freshness as a child. However in northern Europe these days the same niche is occupied by an entirely different variant not present on this page, more akin to a twist-tie (metal covered in plastic, which bends.) Both kinds attach to the same location on the host bread bag, enclosing the mouth of the bag and helpfully holding bread in while preventing airflow. How fascinating to see the same niche, with a different alternative.

ricardobayes• 1 month ago

What are these for? In Europe we normally put a sticker directly on the bread, if at all. Is this for sliced bread?

Sharlin• 1 month ago

I’m pretty sure we have bread in plastic bags in Europe too. At least here in the less civilized regions. In these parts they’re usually the plastic-clad aluminum wire sort though.

WastedCucumber• 1 month ago

We have bread like that even in the more civilized parts.

boomlinde2• 1 month ago

They seem attracted to sliced bread in plastic bags here in the Nordics. They attach to the end of the bag so as to seal and hold it closed, regardless of the labeling on the bag.

There are some positive side effects to this, which is probably the reason we're so tolerant of their presence.

dcminter• 1 month ago

The UK does, or used to, and yes, it was on the plastic wrappers on sliced bread.

Sweden has a wire encased in plastic thing that crimps the opening shut instead.

Both types are re-usable at least for the expected lifetime of a loaf of bread.

ndr42• 1 month ago

Well, if the ecological niches are the same there could be analogous developments that are not homologies. So I without a reconstruction of the environment I'm not certain that the proposed tree is valid.

ErroneousBosh• 1 month ago

This is the sort of top quality nonsense the Internet used to be good at.

We need to go back there.

My grandma had a Paraguayan snuffler (specifically Emunctator sorbens), these parasitoids were his absolute favorite snack.
