| With careful study, exuvia can actually be used to identify the species of dragonfly or damselfly that left them behind. |
| Additionally, presence of exuvia and frass suggest that the moths are emerging late summer or early fall. |
| These exoskeletons, or exuvia, are being collected from the vegetation growing around wetlands and shallow ponds as part of the park's ecological monitoring program. |
| We went into the wadi and took lots of photographs and collected lots of exuviae, which is the husk, the larvae case of the dragonfly, and I collected this funny exuvia. |
| Two days later, we found the shed skin, the exuvia, of a broad-bodied chaser dragonfly beside our small, shallow pond. |
| Strong cryptogeny: the female, with a fine membranous cuticle, remains enclosed in the exuvia of the second larval instar, which thickens and takes on a horn-like shape. |
