While looking for a photo this morning, I found what I knew to be a Cochineal infestation on a Prickly Pear cactus. The history of Cochineal bugs is very interesting if you’ve never heard it. They are a source of red dye considered so highly prized at one time that it was listed on the London and Amsterdam Commodities Exchanges. Click here to read all about it.
We rarely see Cochineal on native cactus. This Prickly Pear was purchased at a nursery.
