Note that the arthropod has 6 legs (to go with my 600th case), indicating that this is a larva rather than nymph or adult.
One reader queried if the components of the collage were from all of my cases to date. Wow, what a great idea! There are more than 4000 images present, which might have been able to represent all of the images from my various cases. However, that is not the case here - the collage is made up of many different arthropods, including bed bugs, ticks, fleas and lice. There is even a pubic louse and a Tunga penetrans flea in there if you look closely (good catch, Florida Fan!).
Old One came up with some additional ideas on how this collage was related to my 600th case:
1.) Wikipedia writes of an unengorged tick gaining 200-600 times its weight after feeding.
2.) King Solomon made a shield of 600 golden shekels. Hard ticks have a scutum (which is a word derived from the latin word scuta which is an oblong shield used by Roman soldiers).
3.) Angel number 600 champions the ideals of family, learning and growing together. We have all grown together with the bounty of knowledge shared over the years on this blog. I also believe that creations, like this wonderful collage (Brava Emily) are like a familial act of kindness.
Finally, Nema reminds us that "This collage of several ectoparasites, implicated in various diseases, should remind us that this week, on July 30th 2020, is the week of the 8th annual ISNTD Bites conference, on vector-borne diseases & vector control, an event that will be held all online."
