After examining dozens of needles very closely, I stumbled across the following specimen which shows a brown needle with an intact green area at the tip.
Even closer examination shows that the brown areas of the needle are in fact hollow, and the needles have been eaten from the inside, thereby killing them. This is indicative of micromoth leaf-miners, and research shows that there are perhaps 8 to 10 candidate species of micromoth which eat Pine needles in this manner. What I need to do next year is to take needle samples with occupant larvae and breed them through to the adult stage for identification.
And yes, the adult micromoths are, indeed, tiny.
So that's it for 2008, the year with the worst weather I can remember. Still, I don't feel too bad: I managed 89 posts, which is roughly one every 4 days. In addition, I was talking to a local gentleman of 87 years, who said it's the worst year for weather in his memory, too.
