Last week of April means it’s time for #InverteFest! This time along with the collections of #invertebrate #sciart, they’ve published an anthology! They paired up authors and illustrators and made a marvellous invertebrate themed online book. Check out our sweet board book introducing the little ones to insect friends, included in the anthology. ‘Meet the Pollinators’ is written by Lisa Jaffe and illustrated by me.

If you need a little microbiology in your fabrics you can find my radiolarians in the minouette Spoonflower shop in a few different colourways. I love their shapes!

Radiolarians (or radiolaria) are a type of tiny creature -amoeboid protozoa which produce mineral skeletons.

They occur as zooplankton throughout the oceans and their tiny skeletal remains can be used as diagnostic fossils to date submarine sediments.

She wrote, “I spent my time investigating insects. [...] I realized that other caterpillars produced beautiful butterflies or moths, and that silkworms did the same.

We need to foster the insects to keep ecosystems functioning. A large percentage of the food we eat depends directly on pollinators. They serve many plants and play important roles in food webs. Pollination makes plants that we and wildlife use for shelter, fuel and which moderate temperature and of course, produce oxygen we need to breathe. Natural habitats around us could not exist without them. Our fate is tied to that of the insects.

This print shows a great little pollinator in the garden: a transverse-banded flower fly (Eristalis transversa) on Echinacea purpurea or purple coneflower.
