My first worker bumblebee (probably Bombus terrestris, but hard to be certain) of the year was gathering pollen from a half-open Dandelion:

I previously showed mites on this page:
Notice that they attach themselves in a place where the transporting insect cannot easily wipe them off, and can also choose precise locations that disguise their presence.
Field Horsetail has pale fertile shoots which precede the green sterile ones:

The cone at the top produces spores which have 4 curved 'legs' that are very responsive to humidity. As the air humidity changes, the legs expand and contract, curling and uncurling. Little hooks at the end catch on to surrounding vegetation, and the spores pull themselves around in different directions order to increase their chances of dispersal. Here's a shot of the spores that I took in 2003:
