Damage caused by Nemorimyza maculosa: A) Feeding/oviposition punctures on leaf surface by adult B) Meandering leaf mine on the left side of a chrysanthemum leaf and the older expanded blotch mine on the right and C) Expanded blotch mine on lettuce (Sources: Luke Smith, iNaturalist (A), Antonio D.

Aulagromyza populi gallery mines on Populus. All shots of the same leaf: upperside full leaf and detail on left (with pupa showing), underside full leaf and detail on right. Humberstone, Leics. (UK) 17/08/2025.

A new miner for me, likely one I've overlooked or ignored in the past. On a tall Lombardy Poplar (or maybe a hybrid Black of some sort). Aulagromyza populi gallery mines with in-situ pupae. These examples show the mine moving from the underside to upperside. #diptera #agromyzidae #panspecieslisting

Reckon this is a Chromatomyia spp. Leaf mine found on Sonchus oleraceus earlier today in a semi rural garden (outskirts of a village) #HumberheadLevels

Hi Rob @vc28wildlife.bsky.social
I’m thinking this might be Agromyza myosotidis, (on Pentaglottis) but the plant is low down and I can’t get a back lit shot of it. Worth recording?

Two trees with moderate infestations of Phytomyza ilicis aka Holly Leafminer (an #Agromyzidae fly) in #Epworth Turbary, a #Lincolnshire Wildlife Trust nature reserve Looks like there will be plenty of flies emerging in May & June but guess a few will be parasitised #HumberheadLevels #IsleOfAxholme

Amauromyza flavifrons Amauromyza flavifrons from Lane County, OR, USA on October 6, 2024 at 03:09 PM by Mike Palmer. reared from Silene coronaria leaf mines. 7667.1

Cerodontha iraeos a common #Agromyzidae leaf-miner of Iris pseudacorus (Yellow Iris) less often seen as an adult. This one swept from the Natural History Museum Gardens

Nice to see two leaf-mining #Agromyzidae flies on the same Solidago virgaurea (goldenrod) plant at the weekend. Nemorimyza posticata (blotch mine) and Ophiomyia maura (linear). Thanks to @AgromyzidaeRS for the ID on the latter

Home for Christmas found some #Agromyzidae. All first records for VC52 Anglesey? Phytomyza ilicis on holly, P. ranunculi on creeping buttercup and Chromatomyia primulae on primrose @AgromyzidaeRS

Broken down awaiting RAC, opportunity for #Agromyzidae recording: Agromyza abiens?, Aulagromyza luteoscutellata, lots of Liriomyza pusilla
