Thanks for the welcome. Lichens sure have a range of colours and they have been used as a source of dyes for thousands of years particularly by the American aboriginal peoples from New Mexico to the Arctic. Also, the earthy russests, browns and yellows of Harris Tweed formely came from lichen dyes. ...

The male florets are the brown anthers with yellow pollen grains; the female florets show 2 recurved red stigma. I believe the red-topped spikes are bracts, one with each f...

Re: Backyard Series #63 (hairy cat)

. I don't have a clue into what this specimen will metamorphose. I do know that it was having quite a feast on the delicate fennel.

Seaside Lichen-2

Image

A general habitat shot from an old Kodachrome slide.
Rock face is about 3 feet; so quite an old lichen.

It may be that there are two species in the three pictures. The first two may be vulgaris with the dark bands on the abdominal tergites more developed than usual. The third is marked more like germanica . Harold (Thanks Rik for the welcome :wink:) I assumed that the photos were 1 specimen; so you m...

Excellent capture of those fine filaments on the side of the abdomen. I have no idea what those do -- never noticed them before I saw these images, but now I see them in some of the BugGuide shots too. --Rik I believe these are hydrofuge hairs and function to hold the bug on the surface while it ta...
