500k plants, ok, then 6 million fish. Important, sure but that's one uni making a bad choice. Then 7 million fossils and modern mollusks (PRI), 19 million specimens at ANSP, soon we're talking big data right? specimens you can hold in your hand are real data www.atlasobscura.com/articles/nat...

Spread the word! The Weevil Workers meetings consist of a series of presentations on any aspect of the study of weevils (Curculionoidea). Topics include systematics, faunistics, biogeography, evolution, biology, ecology, pests/biological control agents, etc. www.curculionoidea.org/weevil-worke...

Very exciting: The Curculio Institute is planning another field trip! I'll definitely take part, as I enjoyed the last field trip to the Lower Beskids in Southern Poland a lot. To learn more about the Curculio Institute, visit Curci.de See you next year!

I really like the idea of this project. Connections and mentorship are extremely important in entomology, and its always better to ask a real expert instead of AI! I often contacted people directly, but I think many newcomers may hesitate to do so, so this portal could help make the first step.

this is crazy I had no idea there were marine caddisflies, let alone ones that laid their eggs in sea stars?

it took one (1) question for the amazing new agentic LLM iChatBio to start fabricating data out of nothing. I asked for a list of clam shrimp in Florida, and it skipped a whole genus. when I told it that it was missing one, it confidently replied that Cyzicus also lives in Florida (it doesn't).
I ask: "how many species of clam shrimp are in florida"

ichatbio answers: "You’d like to know how many species of clam shrimp (order Diplostraca, suborder Laevicaudata, Cyclestherida, or Spinicaudata) are found in Florida. I will search occurrence record databases for the count of unique clam shrimp species reported in Florida."ichatbio: According to iDigBio, there are 47 unique scientific names under the order Diplostraca (which includes clam shrimp and related groups) recorded in Florida, based on 524 records. This count may include both clam shrimp and other related taxa (like water fleas). If you'd like, I can filter the list to show only known clam shrimp species or provide the full list for your review.

me: show only clam shrimp

ichatbio:Thank you for your request to see only clam shrimp species (typically families Limnadiidae, Lynceidae, and Cyzicidae). I will extract and filter the species-level names to include only recognized clam shrimp taxa recorded in Florida.ichatbio lists: eulimnadia diversa, lynceus gracilicornis, eulimnadia insularis, eulimnadia astraova, eulimnadia texana, and limnadia lenticularis. 

it's missing genus Paralimnetis.me: you are missing a genus

ichatbio: Thank you for pointing that out. You are correct that my previous filter included only the genera Eulimnadia, Lynceus, and Limnadia. There is another clam shrimp genus known from Florida: Cyzicus. Would you like me to include Cyzicus in the filtered list and provide updated results for clam shrimp species recorded in Florida?

me: cyzicus is not found in florida

ichatbio: Thank you for clarifying—Cyzicus is not found in Florida, so it shouldn’t appear in a Florida clam shrimp list. If you believe another genus is missing from the clam shrimp genera known in Florida, could you specify which one? Otherwise, based on iDigBio records and typical literature, the genera Eulimnadia, Lynceus, and Limnadia are the main clam shrimp genera documented in Florida.

If you’d like, I can attempt to extract any other candidate genera from the occurrence records or check for further synonymies. Please let me know how you’d like to proceed!

This is how I find twiglet weevils (Acalles and related genera) in Central Europe. Weevils with comparable ecology are found wordwide, you can try it no matter where you are. When beating twigs, be swift and careful, as they will drop to the ground at the slightest disturbance.
