Found out front yesterday?!

Can anyone tell me what is going on in these photos?

This caterpillar was discovered on the bottom side of a leaf. It appears to have all these egg sacks stuck to it's back .. are these some type of parasite?







Thanks Google: here's what I found:
"Frequently hornworms are found with a number of white cocoons attached to its. DO NOT KILL THIS TOMATO WORM! These white sacks are not the caterpillar's eggs--quite the opposite!--the white cocoons are the pupae of the Braconid Wasp. These wasps are parasitic insects that prey on hornworms. These wasps hunt down our garden pests, inject their eggs into their prey where the eggs hatch into larvae and begin eating the internal organs of the hornworm. After these "maggots" have matured they bore through the skin of the hornworm and proceed to spin a cocoon and attach themselves to the worm. From the cocoons emerge adult Braconid Wasp which will begin hunting for other Tomato Hornworms and Tobacco Hornworms to feast upon." - http://www.tammysrecipes.com/tomato_hornworms
