Naar aanleiding van de publicatie van onze checklist van de bladsprietkevers (superfamily Scarabaeoidea) van de Guyana's geef ik daar vanavond een lezing over.

Tonight I'm giving a presentation because of the publication of our checklist of the scarabs (superfamily Scarabaeoidea) of the Guianas.

Cheers, Auke  :)

Other invertebrates - Andere ongewervelden - Autres invertébrés / Unknown organism

Okay, here's a complete mystery to me, which is quite rare by now. A couple of days ago I found several dozen of these things on the beach of Braamspunt (eastside of the mouth of the Suriname River). I presume, for now, that these things have some animal origin, but it could just as well be something plant-based (or of yet some other origin). All of them were about the same size (4-5 cm in diameter), have a slightly wavy outer rim (curved down in the present position) and a somewhat funnel-shaped inner part (facing up here). The ones in the photo are all (nearly) complete; the wide gap in the circular shape is present in all specimens. They are rather floppy and tear easily. When drying out they become rather brittle but maintain their shape quite well. They appear to consist of uniformly very small sand particles (much smaller than what surrounds them in this photo), kitted together with something.

So, what kind of lifeform are these, or what lifeform produces these?

Cheers, Auke

Sorry Paul, it seems I somehow didn't see this post before. Your spider appears to be some Eriophora sp. in the family Araneidae.

I finally found it by myself : this is Nessaea batesii (subsp. magniplaga).

Hi Albert,

Indeed strange. That link was working a while ago. Try observation.org , I think that is the main url for the site. An alternative would be iNaturalist.

Sounds great. First challenge is to get it through winter inside my house.

I love big plants so will do my best with it.
