Giant Mesquite Bug (Thasus neocalifornicus)

The Giant Mesquite Bug (Thasus neocalifornicus) goes through one of nature's more dramatic wardrobe changes. As a nymph, it gathers in dense, conspicuous clusters on mesquite trees, dressed in bright blue, orange, and red. As an adult, it settles into a more sober dark brown-to-black livery with vivid orange markings - still impressive, but considerably more dignified.

Giant Mesquite Bugs feed on the seed pods, leaves, and young stems of mesquite (Prosopis species), using their piercing mouthparts to extract sap and nutrients. They are gregarious insects, with nymphs congregating in large groups that function as a collective warning display - their bright colours advertise the fact that the bugs accumulate distasteful compounds from their host plant. Adults are among the largest true bugs in North America, reaching lengths of around 40mm, and they can produce a noticeable odour when handled.

The close relationship between these bugs and mesquite trees anchors them firmly in the ecology of the American Southwest - a landscape where mesquite has been both a vital resource for indigenous peoples and a subject of intense debate among ranchers who consider it an invasive pest. The Giant Mesquite Bug's dependence on these trees makes it a quiet participant in one of the most long-running ecological arguments in the region, entirely indifferent to human opinions about its host plant.

Bugs Series

Bugs gathers illustrations adapted from and inspired by founder Simon Tyler's book Bugs, published by Pavilion Children’s Books in 2017. The series celebrates the graphic elegance of insect life: armour-like exoskeletons, iridescent wings, compound eyes, and the ingenious mechanics of movement and camouflage. It’s a visual field guide reimagined—clean, bold forms and carefully tuned palettes that bring structure to the surface.

Each piece begins with the research-led drawings from the book and then goes further: refined linework, rebalanced composition, and subtle textural detailing designed for generous print sizes. The aim is clarity and presence — images that feel scientifically grounded yet striking on the wall. Printed with the same archival care as our other series, Bugs turns natural history into crisp, enduring graphic art.

Printing & Materials

Our Bugs series is produced in collaboration with specialist fine-art printing partners using museum-grade 250 gsm archival giclée paper.

Each print is made to order with exceptional precision and colour accuracy, using pigment-based inks for long-term stability and rich tonal depth.

Prints are carefully rolled in acid-free tissue and shipped in rigid cardboard tubes to ensure they arrive in perfect condition, ready for framing.
