spanningtree

Collection of interesting natural things

I took the picture above to see if I could get a good shot of the ocelli - three secondary eyes between the big ones. They are just about visible. Why spanning tree? It's a routing term, from each user's perspective the network looks like a spanning tree - with no loops and only one route to any place. Every user's spanning tree is unique.

Ocelli (again)

I can’t stop taking pictures of bee’s heads – here’s another, fine set of ocelli.


The little chap was dead.



Orchids

Interesting day today with the Box Hill Volunteers, we spotted some interesting orchids… the rare butterfly orchid
and as a bonus extra, a birds nest orchid… this is in full flower and you can see the pollen on the flowers – but it seems devoid of chlorophyll, and apparently derives its energy from a symbiotic relationship with some fungi


I saw this, as yet, unnamed orchid – perhaps a man orchid, but I’m not sure…

and finally… a white Helleborine (Cephalanthera damasonium)
