A rose by another name, the #Willow #Rose #Gall (Rhabdophaga sp) and some bonus smaller tooth like galls caused by (Euura sp) observed in Willow, AK. #midge #sawfly #nature #insects #bug #plant #ecology #botany #entomology

A parasitized willow stem is galled by the Willow Rose Gall (Rhabdophaga sp) causing a green rose like cluster of leaves to grow at the terminal bud and smaller tooth like galls caused by (Euura sp) featuring grean molar like projections with red peaks adjacent to the midvein.

New paper from the Martinson Labs! “Rapid ecological speciation in gall inducers” Where we look at the divergence between Aciurina bigeloviae and A. trixa, two sympatric tephritid flies! doi.org/10.1016/j.ym...

Two flies facing in opposite directions with highly patterned wings.

One of my favorites, I've come across some as big as a tennis ball in UT! Other galls on Artemisia tridentata for folks who are curious: www.gallformers.org/id?h=Artemis...

I've never smelled glechoma so I cannot say, but I have come across a source documenting that the galls of Liposthenes glechomae on Glechoma hederacea have a sweet taste and that people would sometimes eat them: Plant Galls by Redfern, pg 444.

Still one of my favorite captures. A #fireweed bud #gall midge, Dasineura epilobii, oviposits on a fireweed bud next to an associated #parasitic #wasp (Platygastridae) also ovipositing on the same bud. In situ single shot photo. #macro #photography #entomology #enemies #frenemies #nature #darktaxa

A fireweed bud gall midge, Dasineura epilobii, oviposits next to an associated parasitic Platygastrid wasp also ovipositing into the same fireweed bud. The gall midge has two of her legs over the dorsal side of the wasp.

Our research was recently featured on the German TV game show "Wer weiß denn sowas?" ("Who knows?")! The question covered our #discovery of parasitism by the love vine, Cassytha fuliformis, on the gall wasp, Belonocnema fossoria, published in @currentbiology.bsky.social by @cellpress.bsky.social.

One of my favorite activities while at #craft markets or #art shows is to find art of #fireweed, Chamerion angustifolium, and see if the artist unknowingly depicted a flower bud #gall induced by a midge, Dasineura epilobii. Here're some on a fabric print used for a headband by #HappyAK (see arrows).

Densely depicted for weed with flowers, buds, and galls. Normal buds are longer than they are wide while buds that appear as wide or wider than they are long are galled. Three halls are pointed out with arrows. Art by Happy AK.

Back after a hiatus and getting things going again with my favorite pictures showcasing some of the amazing diversity of #Cynipid #galls. #entomology #insects #bugs #wasps #nature #botany #oaks #ecology

Four different types of cynipid galls grow on a gamble oak leaf.
