Clones in a row

Pine needles are tough and don't seem like they should be very appetizing.  Nevertheless, after my close encounter with a western conifer seed bug, I decided to start paying more attention to the pine tree in the backyard.  In one of my searches, I found a needle that had been colonized by aphids.

These aphids can pierce through the pine needle to feed on the sap.  Despite the apparent difficulty of feeding on a needle, they seem to be doing quite well.  When I first found this group of aphids, there were five of them.  When I went back to check three days later, they had already produced three more clonal daughters!
