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!

PERILAMPUS 😍 I hadn't seen one of these stunning blue nuggets in like 3+ years. Perfect, perfect creature. πŸ’™
(they're hyperparasitoids of hyperparasitoids, and so damn cool enough on that merit, but also they can look like this)

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.

just a little baby child (from @mosquitolab.bsky.social's pitfall samples; I can see how this one got sorted into the beetle pile)

The AMNH REU was a life-changing experience for me- definitely consider applying if you’re interested in biology, biodiversity science, or collections-based research!

A faded Ooctonus hemipterus wasp of the Mymaridae found in Combe Valley 31.7.2024. Love those brachypterous wings!

One of Australia's most common and distinctive ants is the colorful Rhytidoponera metallica, seen here with silken cocoons in the brood nest. Diamond Creek, Victoria.

Australian cockroaches are pretty. This is Balta spuria, which I've found in various indoor and outdoor settings in Victoria.

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.

Was reminded of this awesome β€œessay” by T Josek from many moons ago - when us scientists still used the bird website.

T’s use of hashtags here is pretty much perfect. Informative and funny.

Some of the entries are - uhm - timely? (Note: October 1936)
