Am just looking at a collection of Pemphigus spyrothecae Spiral Galls on Lombardy Poplar from Newbury, Berks. They all have a single twist - ie only one crack...
Hi, I'm Sarah, new to the group; I'm a mature student, studying for a degree in Wildlife & Countryside Conservation. A few miles away from where I live,...
Perhaps we need to update Fig. 618 in the keys. Is the lumen inside the gall continuous? I had assumed that it was but, I admit, I haven't dissected the galls!...
Hi Margaret, Yes, the lumen is continuous, but the walls are not; the petiole is swollen and the edges form a good fit to the next turn, but they're not...
Hi, Just entering some old records. Does anyone know what 'Eriophyes pyri var crataegi' refers to? I can't find anything under Crataegus monogyna in the Keys....
Hi Janet, I'm a new guy on the block. :-) Re "Eriophyes pyri" aka Pear Leaf Blister Mite, see http://www.virginiafruit.ento.vt.edu/pearblister.html Section...
Hello everyone, I went to Chris' gall meeting at Evington Arboretum, Leicester last Saturday and amongst the oak galls were several silk buttons but only one...
Hello everyone, I've just uploaded photos into my album of some galls that I found this afternoon, at our local park. I think that they are mite galls: ...
Hello Maggie, This is definitely Vasates quadripedes. In the Netherlands we see it on nearly every Acer saccharinum. The galls sometimes turn bright red and ...
Hi Jojanneke, Thanks for confirming the i/d. It is the first time that I have seen this gall in Leicester, although the Acer saccharinum trees have been in...
Hello all Just a note to invite members to a plant gall and leaf miner recording event in the Epsom area, Surrey, V17. Meet at Ashstead Station 10:30am, Sunday...
Yesterday morning I noticed extensive patches of discolouration of the leaves on Ground Elder in Nottingham University Jubilee Campus. A quick glance suggested...
... Hi Malcolm, I must say it does look very much the same. I usually have the sense to I check your site, but missed it out this. Perhaps it was the...
Hello, Can any of you help identify this gall found on a pear tree leaf in Devon? Would be interesting to know if you are familar with it, and have any...
Hi hengle, It's a gall of the rust Gymnosporangium. There are two spp on pear: G. confusum and G. sabinae, but they can only be distinguished under the ...
Hi Anna, I agree with Malcolm. I have this gall on my cordon pears every year [identified for me by a member of Leics. Fungi Study Group] but have yet to find...
Dear all I am new to this group and am about to start a PhD project involving Cynipid gall wasps and oak trees. During some preliminary work this year I have...
Hello Frazer and welcome to the group My suggestions for your galls, following Redfern et al, 2002, are; A = Andricus solitarius (asexual) mature gall B =...
Hi there, just to add to Frazers pictures: The gall A is about 2-3 times the size of an A. solitarius. Also the tip is somewhat broken off (difficult to see...
Quite right Karsten I should look more closely - I completely missed the size scale! I have a pic of a young fecundator somewhere, I will dig it out for...
Scotty, A. aries with inquilines has occured to me and we should be able to go back, find anotherone and cut it open. However, these were old galls - has...
Hello Frazer, Scotty & Karsten, An interesting discussion...... would it be possible to rear out galls A & B to see what emerges and identify the gall wasps?...
Hello Frazer, The suggested Andricus solitarium (B) by Scotty has several wavy ridges...so is it maybe possible it is Andricus nudus asexual generation, which...
Carl Your specimens arrived safely, despite the postal strike. I was able to retrieve and process two third instar larvae and the two galls were still in...
