|Pupal cases after adults have emerged|
|One of the emerged adult tortricid moths. Note the darker rear half of the wings with paler curved bars to the sides. Length approx 16mm.|
|The second tortricid moth, noting the very different wing pattern. Length approx 20mm.|
|Tortricid egg mass|
|Tortricid moth larva|
So, an unexpected indoor arrival, but a good opportunity to look at a range of stages of its life cycle - I'll leave you with a few more images of the pupal cases.
|The tip of the abdomen of a pupal case of E. postvittana - the hooks (note the curled 'Velcro'-like tips) are used to attach to plants during pupation.|
|Ventral view of an E. postvittana pupa. The antennae are the clearest elongate structures, while the positions of the legs and mouthparts are also visible.|
|An example of how much detail can be seen - as well as the fine sculpturing of the surface of the pupa, and the sutures between segments, a spiracle can be seen bottom right.|
