A moth for #MothWeek! Goat Moth caterpillars are in no rush to become adults – they spend up to 5 years feeding on wood inside trees before pupating #SciArt #NatureIllustration

A gouache and coloured pencil illustration of an adult black-and-white Goat Moth resting on a beige willow branch. In the middle of the branch is a dark gap with a dark red Goat Moth caterpillar inside. The background is a vivid green shade

Caddisfly larvae! Some species build cases from silk + various rocks, plant bits or even shells for protection – some arguably cosier than others Important question: if you were a caddisfly, what would you use to build your case? #SciArt #natureillustration

A gouache illustration of 11 caddisfly larvae in a variety of cases made from sand, gravel, leaves, stems and gastropod shells. The background is painted light blue with visible brush strokes.

One of the benefits of getting up at 4am is getting to sketch moths! First time seeing a Poplar Hawk-moth in the moth trap today :) #SciArt #illustration

A coloured pencil sketch of a moth with grey-blue and brown wings. A hand written text below reads Poplar Hawk-moth.

A blue-grey and brown Poplar Hawk-moth rests on a blotched green and white trunk of a willow tree. The moth rests in its typical position with forewings pointing backwards and hindwings showing at the front.

It’s publication day for my debut book Rocks! 🪨 It is available in many lovely independent booksellers and all the usual bookshops too. Or online here: geni.us/Rocks #geology #SciArt #naturebooks #illustration @quartobooksuk.bsky.social

A beige-coloured book with the title ROCKS on top of the cover, a grey and white striped rock illustration inside a white rectangle in the middle. Below, the subtitle A Guide to the Stones Around Us and the Stories They Tell, and the name of the author-illustrator, Vojta Hybl.

The waterlogged, oxygen-poor soil means that when plants die, they slowly turn into peat. Healthy peatlands store vast amounts of carbon but commercial cutting, burning and draining have degraded them. Dry, exposed peat releases CO2 back into the atmosphere, which contributes to the climate crisis.

This painting is a cross-section through a blanket bog: Sphagnum mosses carpet the dark peat below, which rests on metamorphic rock. It’s an archive of time: from minutes to billions of years. #sciart #natureillustration #illustration #gouache

A gouache and coloured pencil illustration showing a cross-section view of a blanket bog. On top are living green and red Sphagnum mosses; in the muddle a dark brown layer of peat; the bottom shows a stripy grey and light layer of folded metamorphic gneiss.

It also has non-standard guidebook features like: – the etymology of every rock name – a more philosophical take on the rock cycle – an entry on the confusing existence of dolomite (the rock) and dolomite (the mineral) – lithic mindfulness – sneaky Lady Gaga and The Weather Girls references

It has over 100 different rocks: there are sections for igneous, volcaniclastic, sedimentary, metamorphic and anthropic (rocks influenced or made by humans) – something no other geology guide has. Expect ID tips, notes on its formation, and what that can tell us about the Earth’s geological past

POV: you are in Scotland but it’s 400 million years ago and also you are a tiny springtail #sciart #illustration #paleoart #kidlitart #natureart

A gouache illustration of the ecosystem of Rhynie Chert in Scotland.

In this illustration are a few inhabitants of ancient Rhynie: Asteroxylon (a green club-like plant) and Rhynia (plants with pink tips, where it released spores from) on land. In the water on the right, two red, shrimp-like Lepidocaris rhyniensis swim around Palaeonitella algae. They grow on top an older, already petrified ecosystem – the dark shapes are the solidified plant stems so typical for Rhynie Chert.

In the background are reddish mountains and a grey, rainy sky.

The coloured bars underlying the dates correspond to the official chronostratigraphic chart, so it’s even easier to know where in the year / geological deep time you are on any given day!

Each day of 2026 corresponds to 12,512,329 years of our planet’s geological history. I highlighted different geological events throughout the months to help you visualise the unimaginable timescales of deep time (it makes for a great science communication or educational tool as well) #geology

My new illustration of an iconic tundra bird – the rock ptarmigan! It traces the colour of their feathers throughout the changing seasons #sciart #nature

A gouache illustration of a male rock ptarmigan (Lagopus muta) sitting against ultramarine blue sky. There are four windows showing the bird change the plumage colour with the seasons. In autumn, they are grey to blend in with the rocks. In winter, the feathers moult into a snowy white. In spring and summer, the colour transitions into a mottled grey-brown to hide them in vegetation.
