Hi Richard, Who's got a Coolpix? ;o) Most rust aeciospores look very similar. The differences between those of these two species are very subtle. You'll need...

Hi Keith, I asked the gall finder about the larvae, so maybe we will know some more soon! Last Thursday I received a gall from the Gerendal in the far south of...
Seemingly, I have found both Eriophyes inangulia and Eriophyes laevis on Alnus leaves according to 'British Plant Galls'. The ones I have found (in south...
This gall seems to be very common on hawthorn this year - at least in valleys of the Wite Peak, e.g. Tideswell Dale. The species is clavariiforme though ...

Yesterday I found a young Ash - Fagus sylvatica - with many leaves galled by, what would appear to be, Phegomyia fagicola although the galls are along the...
