During a visit around Mavronero Farm, we came across an unusual sight: a large, bright green caterpillar moving across the gravel. Its vivid blue markings, white spots and yellow-green body immediately caught our attention.<\/p>\n\n\n\n
The caterpillar was on the ground, where it could have been vulnerable to being stepped on or otherwise disturbed. To reduce this risk, we carefully moved it onto a nearby plant.<\/p>\n\n\n\n
This small encounter gave us an opportunity to observe one of the striking insects found in the Mediterranean region and learn more about its life cycle.<\/p>\n\n\n\n
The caterpillar is identifiable as the oleander hawk-moth (Daphnis nerii<\/em>), a member of the hawk-moth family, Sphingidae.<\/p>\n\n\n\n The species occurs across parts of Africa and Asia and the warmer regions of Europe, including the Mediterranean. Its adult form is a large moth with intricately patterned wings in shades of green, olive and other muted colours.<\/p>\n\n\n\n The caterpillar is equally remarkable, with a distinctive appearance that makes it particularly interesting to observe.<\/p>\n\n\n\n One of its most striking features is the pair of blue and white markings near the front of its body. These resemble large eyes, but they are eyespots rather than actual eyes<\/strong>.<\/p>\n\n\n\n These markings are thought to serve a defensive function. When threatened, the caterpillar can adopt a posture that makes its front body segments appear larger, emphasising the eyespots and potentially discouraging predators.<\/p>\n\n\n\n Another recognisable feature is the small horn at the rear of its body. This is characteristic of many hawk-moth caterpillars and is not a stinger.<\/p>\n\n\n\n Its green colour, pale markings and eye-like spots make it a fascinating example of how insect appearance can play a role in interactions with potential predators.<\/p>\n\n\n\n As its common name suggests, this species is strongly associated with oleander (Nerium oleander<\/em>), a shrub widely grown in Mediterranean gardens and landscapes.<\/p>\n\n\n\n The caterpillars feed on the leaves of oleander. They can also use other host plants, including plants in the periwinkle group (Vinca<\/em> species).<\/p>\n\n\n\n This relationship is particularly interesting because oleander contains toxic compounds. The caterpillar is adapted to feed on this plant, although the precise consequences of its diet for its own chemical defences should not be assumed without species-specific evidence.<\/p>\n\n\n\n We have not confirmed whether the plant onto which we moved the caterpillar at Mavronero was a suitable food plant. Its presence on the plant was an attempt to move it away from a potentially dangerous position, rather than a confirmed identification of its preferred host.<\/p>\n\n\n\nWhy does the caterpillar look like it has eyes?<\/h2>\n\n\n\n
