I've been seeing a lot of "well I guess this is the way things are now" "ah another line of evidence that we are a fallen empire", attitude that I am begging people to shake off. There are people working their butts off to make things better. Please don't give up. Join us.

The world is a sh*tshow right now so I'm posting this #WaspWednesday image a day early. It's Conura sp., collected in central Texas, and I'll add the obligatory "never missed leg day at the gym" comment. #NaturalHistoryCollections #FocusStacking #Hymenoptera #Chalcididae
Left lateral view of a small point-mounted wasp, against a dark grey background. This parasitic wasp is predominantly yellow, with orangish tints on the legs and metasoma. There are also a few scattered dark brown markings. As a chalcidid wasp, it's characterized by ridiculously enlarged hind coxae and femorae.

Good article, but the framing is wrong. There is not a dearth of interest in taxonomy. There is a scarcity of funding and positions, which is a deliberate choice by funding agencies and institutions. The youth love taxonomy! It's the olds that are failing to meet their passion!

teeny tiny wingless parasitic wasp, probably genus Baeus. It is so round and fat and perfect. Its head is the size of the rest of its body.

17. Contrasting wood cockroach There's so many species of blattodeans (cockroaches & termites,) with v few being considered pests by humans. Some are incredibly colourful, some are metallic & shiny like jewel-beetles, others have bold patterns. They're very underrated. #SciArt #ArtAdventCalendar
A colour pencil and watercolour drawing of a contrasting wood cockroach, Eushelfordia pica. It's got a teardrop shaped body, black with bold, blocky patches of white and orange. It has a small head with antennas that look like beads on wires. Delightful.
