Harmony in the hive? Think again! 🐝⚔️

Insect societies are famous for cooperation, but beneath the surface lies a brutal conflict over who gets to wear the crown!

Our new review in Biological Reviews explores the evolutionary battleground caused by such caste fate conflict. 🧵

These wood ants are edge specialists... but not all edges are equal. Jacob Podesta used a decade of population expansion data to show that wood ants spread more quickly along certain edges, depending on the edge orientation. Currently available open access here:

#Haplodiploid inheritance is found in all species of #Hymenoptera. @mwbstr.bsky.social &co map the #sex determining #gene of the red mason #bee to the ANTSR gene region, suggesting a shared, ancient origin of #SexDetermination in bees & ants >150 Mya ago @plosbiology.org 🧪 plos.io/47COEtH
Complementary sex determination (CSD) in bees and ants. Top left: Single-locus CSD is likely to be the predominant mode of sex determination in Hymenoptera. CSD loci have been identified in two species: the honeybee Apis mellifera and the invasive ant Linepithema humile. The tree shows evolutionary relationships between these species and Osmia bicornis, the main subject of this study. The origin of Hymenoptera is estimated as 386 million years ago and the common ancestor of Apoidea and Formicoidea is estimated as 153 million years ago. Top right: Under single-locus CSD, females are heterozygous at the CSD locus, whereas males are haploid and therefore hemizygous. A large number of CSD alleles are expected to segregate in outbred populations. A small proportion of homozygotes at the CSD locus are produced by chance, when parents share an allele, which results in the production of sterile diploid males. Middle: An O. bicornis nest consists of a row of cocoons in a tube. The mother lays fertilized diploid eggs deepest in the nest and unfertilized haploid eggs closer to the entrance. Eggs develop into adults inside cocoons. Diploid eggs typically develop into females whereas haploid eggs become male. A small proportion of diploids that are homozygous at the CSD locus develop into diploid males, which occur amongst females and are larger than haploid males.

Tho this the first w/ soft parts too, instead of only the shell!

Day 12 of #invertober2025 is the Pacific razor clam
A vectorial digital drawing of a Siliqua patula, or Pacific Razor Clam, set against a pale blue background. The clam is shown extending its large, fleshy pale cream-colored siphon from one end of its shell. The shell itself is long, narrow, and slightly curved, with a glossy appearance. It is colored in shades of golden-brown and tan, featuring distinct concentric growth rings that run perpendicular to its length. The text "invertobter2025 - Day 12" is in the bottom right corner.
