Not a Pleasant Sight

What's wrong with this photo?

A honey bee is nectaring a lavender, right? 


But if you look closely, you'll see a Varroa mite--a parasite--attached to her.  

Varroa mites, considered the No. 1 pest in the honey bee industry, are linked to colony collapse disorder, a mysterious phenomenon characterized by adult bees abandoning the hive, leaving behind food stores and the brood.

Varroa mites are so common that it's rare to find a hive without them.

Female mites reproduce inside brood cells in the hive. Mites suck the bee blood or hemolymph; in doing so, they spread viruses, stunt the growth and cause deformities. 

Within two years, they can destroy a colony. 

Not a pleasant sight.
