Another bug, more eyes

Category: animals

I’ve been on a bug streak lately.

In the last post I mentioned ocelli, because they were so prominent in the image of the mantis.  Here is another bug – a cicada - showing prominent ocelli, or accessory eyes.  You can see them on the ‘forehead” in between the prominent red compound eyes.  This individual has recently emerged from its nymph stage (leaving the characteristic shell, not shown).  I had this one in a jar and watched the entire sequence unfold.  You can see that its wings have not completely “inflated” yet.

As a nymph, the cicada had no ocelli.  This is because the nymphs don’t have wings; the ocelli function mainly as flying aids. I took this shot in 2004 during the emergence of brood X.
