A gift reading through Prigogine's 'Order out of Chaos' is his processual framing of science. From the Ancients, through to Newton, Hamiltonian, the complex thermodynamics of Maxwell, thereafter quantum mechanics. Accompanying this then, not only the historicity of processual science but philosophy

Fast signalling, thus associated complexity, is only made possible by dissipative structures incurring extreme entropy production. Of these at every level, autocatalytic reactions being most effective. Without high coupled entropy -TxΔSi to irreversible calcium signals in fertilisation for instance,

1/8: Thermodynamics influenced my viewing open biological systems similarly. My workings how I use Gibbs as primary metric, calculating 'human dissipative structure Fitness' against 'net biodiversity dissipative structure Fitness' over 'closed Earth system': H=U+pV ΔU = q + w

Neotropical Cassida sp. from top right I think. Precisely why Coleoptera are so speciose, and formidably adaptive as an order. Their sclerotised elytra/pronota unlocked diverse habitats, denied to most other Insects. The physiological quirk (via mRNA) for quinones repurposed then sent to the

Phenotypic plasticity is all the rage when defining convergent evolution at the macroscale. Very seldom do nucleotide bases randomly assort, thereafter selected by convergent evolution at the microscale. Here's one such example, however: www.biorxiv.org/content/10.1...

I explored #Ancient Hodgemoor Woods late last night (#Chilterns, UK) and came upon this #rare #Symphytan:

Very pleased my two Dolerus sp. are healthy and thriving, currently morphed from eonymphs to prepupae. I found this small pop. of rare Tenthredinidae larvae in an ancient woods (Northmoor Hill Wood, Denham UK). Interesting too whether they overwinter as pupae or emerge this year:

A twitter post today made me unexpectantly sad. The last known recording of a male Kauaʻi ʻōʻō (1987), calling out for a mate that would never come. He died alone, and the species went extinct. So I wrote a poem:

Platystomos albinus, Anthribidae, 16/7/25, Denham Lock Wood, UK. I found this specimen climbing an ancient alder tree, it engages in thanatosis when startled. Quite a scarce species.

Ichneumon suspiciosus, Ichneumonidae, 9/7/25, Denham Lock Wood, UK. A tentative ID, would appreciate any suggestions please @gavinbroad.bsky.social?

But also reduces associative fixation with cereals like switchgrass. See this great paper from Michael Udvardi, for instance: apsjournals.apsnet.org/doi/10.1094/...

@jeanmichelane.bsky.social So similarly would infusion of fixed nitrogen inhibit enzymic nitrogen fixation within rhizomes (& associated bacteria)? Or as the chloroplasts (formerly cyanobacteria) are well endosymbiosed, whereas the symbiotic root bacteria nph.onlinelibrary.wiley.com/doi/10.1111/...

Worrying development, and another cause of human ecological disturbance. The ‘triboelectric effect’ is well known in slightly ionising cuticular surface of insects (friction by rapid wing movement etc). Yet now the coadapted electrostatic attraction to partially negatively charged angiosperm plants

THE COLEOPTERISTS EVOLUTIONARY TOOLKIT: HOW TO ASSEMBLE YOUR BEETLE FROM A PRIMORDIAL CHEMISTRY

An old photo I took during my first field season with a macro lens - checks notes - ahem, 20 years ago, in May 2005. I hadn’t discovered flash diffusion yet. But it’s a rarely witnessed scene: Eciton burchellii army ant workers collective carry a massive male larva. Henri Pittier NP, 🇻🇪.

I reckon alderflies (Sialis lutaria) would be great at playing Twister.

Staphylinidae, Othius punctulatus, Hodgemoor Woods, United Kingdom, 3/7/23: Hodgemoor Woods is an ancient old-growth forest in the heart of the Chilterns. Fungal growth between ventrites and dorsal tergites, exposed thanks to Staph. abbreviated elytra, as previously identified.

A #bee was roaming the sidewalk aimlessly so I caught it for pics. It died 😭 but upon closer inspection there were live hitchhikers: #triungulins! Prob. blister beetles (Meloidae), they were tightly gripping hairs to ride the bee back to its nest, where they become grubs feeding on pollen & larvae.

I ended up spending six weeks with this colony, following its nightly emigrations through the Venezuelan cloud forest and documenting its behavior. At the end it took us almost an hour each way to just get to the colony. The resulting report is here: link.springer.com/article/10.1...

When they emigrate, army ants move their entire colony, including the workers and queen (diploid) and, in cases where haploid males are present, the males as well. In “phasic” army ants, like Eciton, colonies relocate almost every night during the nomadic phase.

Instantly I can see metalloporphyrins shares similar features of four covalent ligands donated by delocalised nitrogen atoms - to a central magnesium ion. The same electronic properties as chlorophyl molecules. What are they trying to emulate? Will be interesting reading @jeanmichelane.bsky.social:

Beauty in the compound eye of the beholder. Calopteryx splendens (male), Calopterygidae, 30/4/23, Denham Lock Wood, UK:

I wrote a post (9/4/25) suggesting Manticora species (Cicindelidae, Manticora tyrranus) as successful Batesian mimics of certain desert Tenebrionids. This upon viewing a recent twitter post, depicting images of supposed Namibian Tenebrionid, with starkly similar morphology. I was informed by the

I was thinking today about the successful Batesian mimicry of Manticora species (Cicindelidae) in relation to desert Tenebrionids (in particular Pimelia sp.), across the shared hostile, arid environment of Namibia. There was a twitter post on Manticora morphology and immediately

This #Neochlamisus larva wears armor made from its own frass, yes, it builds a protective case from excrement. These camouflaged tanks belong to the #Chrysomelidae family and blend into foliage with surprising success. 🌿 #macrophotography #entomology #coleoptera #bugsky #invertebrates

@mcaterino.bsky.social I sent you this on twitter for an interesting find for your take "Is this a Cicindelid Manticorini species or the potential Tenebrionid they seek to mimic? This species is also from Namibia, so overlapping territory and spatial/temporal stage for Natural Selection to exploit."

Happy π day!! The most important π in chemistry, the π bond. The non-localised π electron cloud in the porphyrin ring of chlorophyll, not only frees up lone electron pairs in the 4 nitrogen atoms, producing 4 ligand coordinated sigma bonds donated to the central Mg2+ ion. Fine tuning their combined

@wkcosmo.bsky.social Anisotropic birefringence of this Scarab's cuticle is biophysics in action! Organic nanostructures cause a π/2 phase shift (~90°) between two components of the electric field, and r/l elliptical photon polarisation. Scrambling the visual stimulus of predators. Details here:

Chemical cross-links form the sclerotised tissue primarily of pronota/elytra, yet other extraneous sclerites (lateral thoracic pleurites etc), across diverse Order of Coleoptera. Specifically, covalently bonded cross-links between peptide chains (proteins), chitin (glucose derivation), and the

I think this is a testable hypothesis. The stored metabolic product of quinones internally (ie vestibule pool), that would otherwise be used as the cross link agent in sclerotised elytra/pronotum, which via random mutations (regulatory pleiotropic alleles controlling quinone allocation) were instead

So I was thinking this morning about how the sclerotised tissue of pronota, elytra (plus sclerites in form of lateral pleurites etc) are formed by chemical cross links. Specifically, covalently bonded cross links between peptide chains (proteins), chitin (glucose derivation), and the oxidation of

I was thinking this morning there's an inherent difference between quantum physics and quantum mechanics, isn't there in terms of terminology? Quantum physics is universal, and the physical laws of which are objective, and underpin all of reality and everything it contains at the subatomic particle

The inverse of my earlier post, where the hooded pronotum overhangs the epicranium/frons (inflated anterior edge) across Scolytinae and Bostrichidae. Where instead, the pronotum of Liatongus rhadamistus (Scarabaeidae) overlaps the entire mesothorax and metathorax. This extreme misalignment shows
