Tyria jacobaeae - caterpillar

Posted by Johan Dierckx (Wijnegem, Belgium) on 29 June 2010 in Animal & Insect and Portfolio.

Tyria jacobaeae (Cinnabar moth / Sint-jacobsvlinder) is a brightly coloured moth belonging to the family Arctiidae. The larvae use members of the genus Senecio as foodplants. Many members of the genus have been recorded as foodplants but for long term population success the presence of the larger species such as ragwort is needed. Initially the larvae are pale yellow but later larval stages develop the jet black and orange/yellow striped colouring . They feed ravenously and can grow up to 30mm. Cinnabar caterpillars are voracious eaters and large populations can strip entire patches of ragwort clean, a result of their low predation. That is why sometimes these caterpillars are used to control populations of the poisonous ragworth.
In this image I find the balance of the two caterpillars on a tiny grass plant... one going up, the other going down... extroardinary.

@♏arleen: Ik wist wel dat deze rupsen behaard waren, maar dat die haren zo lang zijn, was me tot hiertoe nog nooit opgevallen.

Dutçh from Chicagoland, United States

I love the coloration! Superb capture.. I would think their 'camo' isn't too camouflaged though.

@Dutçh: The 'camo' is not very effective indeed ... but the coloring says ... "I'm harmfull and not tasty at all" (pattern and coloring looks a bit like huge wasps ... It's just a different way of using colors :-) Maybe we should pay some more attention on these effects in our own dressing code ;-))

Julie Brown from Indianapolis, United States
