I’ll post some cacao flowers when the sun comes up.
bat pollinated flowers are almost always large and tubular. because bats are large, at least relative to insects, and even then, I don’t think a bee could successfully pollinate a cacao. suns up in 1hr.
This is a cacao flower. It’s about 5 mm wide (half a centimeter). It has no visible nectaries, and it seems like the pollen are in pollenia attached and guarded by anther shields. Like wise, the stigma has some filimants (maybe infertile anthers?) that also appear to be for blocking self pollination. None of that speaks to bat pollination and unlikely even pollination by European honey bees. This kind of floral arrangement would speak to a specific species that needs to be just the right size to get a pollenia stuck to it, then to be able to move that polenia past the filaments around the stigma on another flower. More akin to an orchid or milkweed style of pollination.
(uploading a video too, but it will be a few minutes)

I looked them up as soon as I saw your comment and actually saw a midge on the edge of one, so I totally agree.
Just wondering what the kernel of truth all of these listicles are referencing is.

Makes sense, there’s no evidence I can find that bats pollinate them either, just broad statements and puff pieces and listicles.
Thanks for posting the pictures though, that’ll be interesting for anyone visiting this thread
Here is the video, just posted
