Halloween News: Meet a new vampire fly (Hippoboscidae) 🧛‍♂🪰 1 of 10 species found on citizen-reported bird carcasses in Singapore: Even dead birds can have productive afterlives! See host records, annotated images, pictorial keys & DNA diagnostics here: doi.org/10.1155/jzs/...

Fresh preprint on how to optimize quality of voucher DNA remaining in insect specimen after barcoding; from @rudolf-meier.bsky.social and our lab. www.biorxiv.org/content/10.1...

I'm having fun exploring ways to visualise the history of BINs in @boldsystems.bsky.social using #graphviz Below is the history of BOLD:AAH8697 which is a BIN highlighted by @rudolf-meier.bsky.social in doi.org/10.1111/cla..... Columns are time-slices and the coloured boxes are bins.

The top 10 flying insect clades rule the skies—but defy the rules. Weak or inverted latitudinal diversity gradients leave biogeographers puzzled. Entomologists? Mildly amused. www.biorxiv.org/content/10.1...

🚫 Farewell to species descriptions with consensus barcodes. ✨ Hello to Diagnostic Molecular Combinations (DMCs) for your taxonomic research ✅ State-specific ✅ Contrastive ✅ Publication-ready Now even easier with the latest UITOTO, our updated user-friendly software; Preprint: doi.org/10.1101/2025...

UITOTO for taxonomy. Get your molecular diagnoses right without coding or breaking a sweat! Use state-specific, contrastive DMCs instead of fuzzy consensus barcodes! 🪰🦋🪱🦎🦀🐌🦉 doi.org/10.1101/2025...

🚨 EntoSieve is now published in Molecular Ecology Resources: Fast and accurate size-sorting of bulk insect samples! Perfect for boosting DNA megabarcoding & metabarcoding projects. 🧬🔬 DIY low-cost device, gentle on specimens and yet efficient 🦋🐞 here: onlinelibrary.wiley.com/doi/full/10....

Species- versus specimen-level congruence between DNA barcodes and morphology. Species-level dominates papers but specimen-level matters more for sample evaluation. Read more in "Illuminating Entomological Dark Matter with DNA Barcodes..." in Ann Rev Ent: www.annualreviews.org/content/jour...

Dark Taxonomy: From unknown to ready for biomonitoring in 5 steps. By describing 120 species, most species of fungus gnats routinely caught in Malaise traps in Singapore now have names. Bees, butterflies and birds, make room for your new friends. Read here: onlinelibrary.wiley.com/doi/10.1111/...
