Sam Thomas @sjthomasbotany.bsky.social · 03/06/2026Huge congrats to @jasboparai.bsky.social on what I'm sure will be an essential book for an underworked group. But absolute shame on CABI & @royentsoc.bsky.social for their new pricing. £125 for a 25-species handbook is unreasonable and will prevent it from reaching its deserved audience.tinyurl.comThe Darwin Wasps of the British Isles – Tribe Pimplini (family Ichneumonidae, subfamily Pimplinae) | CABI Books 3181
