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.

The Ommatidium Project@entofacet.org · 3w ago

Our expert pool is growing, from Acari to Psylloidea. With the help and passion of the invertebrate science community, we hope to create a home for connections across the field. It’s also free and a passion project to help the community. Not a side hustle. #entomology #inverts

Square dark navy promotional graphic for EntoFacet. At the top is the EntoFacet compound-eye logo: six deep-blue circles around an iridescent blue-purple centre. Large cream serif text asks, “What is The Ommatidium Project?” Below, pale blue text reads, “A better front door to entomology. We help connect people with the right volunteer, society, collection, or expert.” Three outlined boxes give example questions: “How do I get started in a museum or collection?”, “Can you help me find a local society or field day?”, and “Do you know someone who works on this insect?” At the bottom, large blue-purple text reads “entofacet.org,” followed by “More questions, from insect IDs to expert referrals.”

Curculionidae of the World Online has moved to a new URL: catalog.curculionoidea.org The old URL can still be accessed. We are working on a better and more detailed representation of the relationships between weevils and their host plants. Expect some really nice things in the near future!

Curculionidae of the World Online

Curculionidae of the World Online is a collaborative taxonomic catalog of weevils, built on TaxonWorks. It provides curated data on taxonomy, distribution, biological relationships, as well as images ...

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!

Meet Peltophorus polymitus, the Agave Stem Weevil! - Larvae develop in the stem of different Agave species (often A. palmeri) - When disturbed, the weevils will drop into the thorny depth of their host plant - found in Mexico and the SW of the USA - This specimen was found by Salvatore S. Anzaldo

How to find Mogulones crucifer: The weevil is native to Europe/West Asia, but has been introduced to North America to control its host (Cynoglossum officinale; Hound's Tongue) which is invasive there.
