Number of ommatidia dragonfly

How many ommatidia does a dragonfly have?

30000

It is important to understand that the number of ommatidia in the eye depends upon the type of insect and ranges from just a few in the primitive Archaeognatha and Thysanura to around 30 thousand in larger dragonflies.  Do not look surprised!  According to the website www.dragonfly-site.com, 30000 represents the number of ommatidia that dragonflies have within their compound eyes.  The most interesting part is that each Ommatidia, called Ommatidium in singular, is an eye in itself.  This signifies that it is capable of seeing anything right in front of it.  Moreover, this attribute helps the dragonfly sense movement anywhere around it.
