Cassida rubiginosa  |
||
| Cassida rubiginosa (often known as the Green Tortoise Beetle) is a common leaf beetle on Creeping Thistle and Knapweed throughout Nottinghamshire and is certainly the most likely of all the Cassida species to be found. The body of the adult is totally covered by the extensive elytra and pronutum, helping eliminate all shadows and aid camouflage on the leaf surface. The flat, almost slug-like larva has rows of branched spines along it's outer edge and has the habit of deficating onto it's back. Larva (below right photo) are easily found during June and the adults appear from mid-July onwards and over-winter. | ||
