Calvisia kneubuehleri is one of the most striking stick insects in the hobby, instantly recognisable for its bold, painterly colours. Originating from the seasonal forests of southern Vietnam, this species displays vivid contrasts of black, yellow, blue and red, earning it the nickname “Picasso stick insect.” Both sexes are fully winged, with females showing deep carmine hindwings and males carrying a slimmer, more lightly marked frame.
 
In captivity, C. kneubuehleri is manageable but benefits from stable conditions. It prefers temperatures below 25°C, high humidity, and good airflow. Cherry laurel is the most reliable foodplant, though willow is accepted by some lines. Females lay neat rows of barrel‑shaped eggs, which typically hatch after 8–10 weeks. Nymphs begin life in soft yellow‑green tones before developing their adult colour palette.
 
This species remains uncommon due to its limited wild range and sensitivity to environmental fluctuations, but established breeding lines are now available. When kept correctly, Calvisia kneubuehleri rewards the keeper with exceptional beauty, engaging behaviour, and a truly unique addition to any phasmid collection.
