Spaceways<p>30/08/2025 - A new gall for me today. The proper grim looking alder tongue gall.

Spaceways<p>25/08/2025 - Sunny walk amongst the trees today. The wood-sorrel is always nice to see. I like to check the oaks for galls.

Gina<p>California Gall Wasp (Andricus quercuscalifornicus) is one of the largest cynipid wasps (5mm!) and induces the largest insect galls in the western U.S. Some females emerge between August and November, while others may remain in the gall for over a year before emerging.</p><p><a href="https://sfba.social/tags/cynipidwasps" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cynipidwasps</span></a> <a href="https://sfba.social/tags/galls" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>galls</span></a> <a href="https://sfba.social/tags/nature" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>nature</span></a> <a href="https://sfba.social/tags/wildlife" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>wildlife</span></a> <a href="https://sfba.social/tags/california" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>california</span></a></p>

Spaceways<p>12/07/2025 - Morning walk before it got too hot. It was still a bit warm for me. Everything really looked lovely in the sunshine though. Up and round the hill. Just me as Mrs Spaceways isn't back until later today. I took my butties and found a shady spot with a view down to the river to sit and have my lunch. Kestrel overhead and yellowhammers calling. It was a nice 4hrs out.</p><p><a href="https://toot.community/tags/SunnyDay" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SunnyDay</span></a> <a href="https://toot.community/tags/MorningWalk" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MorningWalk</span></a> <a href="https://toot.community/tags/Wildflowers" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Wildflowers</span></a> <a href="https://toot.community/tags/Galls" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Galls</span></a></p>

Kimberley<p>Lots of galls have appeared on the local oak trees looking like droplets of red juice. I’m not very knowledgeable on galls. I think it’s a type of spangle gall, iNat suggests pea gall wasp made them (Cynips divisa). <br><a href="https://ecoevo.social/tags/Wasps" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Wasps</span></a> <a href="https://ecoevo.social/tags/Galls" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Galls</span></a> <a href="https://ecoevo.social/tags/UKNature" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>UKNature</span></a></p>

neville park<p>Best discovery at this weekend's yard sale day: I saw a bunch of tiny orange midges swarming around certain shrubs in people's yards. Looking closer, I saw they were molting from galls on the undersides of the leaves—often in bundles of three or four, leaving empty exuviae behind. Many were mating, presumably about to start the cycle all over again. </p><p>Just got around to looking it up. They are boxwood leaf miners, a kind of gall midge (family Cecidomyiidae).
