Historically galling
With the crocus shoots up—no bud blossoms yet... and no sign of hungry deer—my attention has turned groundward, so I'm spotting things I would have otherwise missed. Case in point: these oak-leaf galls that have clearly hatched and given rise to a new generation of gall-makers. I don't know precisely what manner of invertebrate made them by irritating the leaf tissue then laying an egg in the resulting tumor—the gall is essentially a stocked refrigerator for an invert kid—but the culprit is often a kind of tiny wasp. (It could also be a beetle, butterfly, aphid, thrips, fly, or mite.) No doubt, if I continue to look, I'll find other galls, and equally no doubt, there'll be more gall-makers at work once the growing season gets underway.
