Brood X Cicadas in the Morning

A split in its exoskeleton forms between the eyes to the end of
the thorax and widens as the cicada frees its head at 7:41 a.m. and 7:50 a.m.

These pictures were taken an hour and twenty minutes apart.
By 8:12 a.m. the cicada’s body was light gray and wings were
fully expanded. Soon after, it began its climb up the trunk
of a large oak tree. Photo © Mary Free

A cicada makes its way up an oak tree trunk at 8:45 a.m.,
passing one struggling to molt. The latter was unsuccessful as
it had damaged its soft left wing and could not free it. Its body
hardened, trapped inside the exoskeleton. Photo © Mary Free

These pictures were taken between 7:03–7:30 a.m. The cicada
finally frees itself around 7:52 a.m., but instead of grabbing its
exoskeleton to pull itself out, it dropped a couple of feet to the ground below.

This cicada has just emerged from its exoskelton at 8:35 a.m.
Its wings will eventually expand and
its body will turn black as it hardens.

For some cicadas, the molting process can be long and arduous, taking up to an hour or more. After the nymph emerges from the ground and chooses a spot (usually one that is vertical, on a plant leaf or stem or tree trunk), a split in its exoskeleton forms between its eyes to the end of the thorax. It removes its head first and then vibrates the rest of its body out, until it is in an upside-down position. Its body is soft and wings are especially vulnerable during this time. The cicada can damage them as it struggles to free itself, or in a fall, if it fails to grab the exoskeleton and pull itself out, and drops down instead.
