The fuzzy nautilus (Allonautilus scrobiculatus) was thought to have gone extinct back in 1986, until Peter Ward spotted one again in 2015! These nautiluses have a distinct thick, slimy, yellow fuzz covering their shell called a periostracum.

How many insects can you see in this photo? Believe it or not, there are five. This termite alate fell victim to four perfectly camouflaged assassin bug nymphs (Reduvius tarsatus) Their bodies are covered with minute setae that trap grains of sand and various debris, making them virtually disappear.

This katydid from Ecuador has been affectionately named by photographers "candy-cane katydid". The truth is... we are not sure which species it is. One possibility is a Harroweria nymph, but until someone witnesses the transformation into the adult stage it will remain a mystery.

Old friend just laid off by USDA, 1 mos short of his probationary period as senior researcher. Brilliant person who left a tenured faculty position several yrs ago to join USDA. Bright early-career researchers also being laid off. USDA is terminating a generation of highly-qualified scientists.

A consequence I didn’t expect from many federal workers in #entomology losing their jobs was the sudden loss of data, new species images and keys. Normally, they have time to gather taxonomic keys or images for publication, but since they were terminated abruptly, that material is now locked.

USDA firing the newest hires across the board means they are purging experts relevant to new and emerging threats; e.g., people who combat the Citrus Greening disease that's collapsing Florida's citrus industry. Just the dumbest strategy imaginable. Unless the goal is to collapse the US.

Whip spider (Paraphrynus laevifrons) covered with chloropid fly puparia. The parasitoid fly attacks the eggs carried by the female. When done, the maggots climb on the "childless" mom's back and pupate. She protects them during this period thanks to her motherly instincts.
