The butterflies were out in abundance yesterday.  I had never seen so many butterflies out all at once!  My neighbour had called me up to her house to photograph all the butterflies in her backyard.  Most of the butterflies were red admirals.  There were also a few question mark butterflies as well.  That is not a question by the way... the butterfly is actually called the question mark!    It seemed a lot of mating was going on... it must be Spring! 

While taking some pictures of a particular red admiral, I noticed that it had a piece of fluff on its leg.  I was actually a little disappointed, as I thought that it would detract from the photo I was attempting to make.  I managed about five shots of it before it flew off, and then continued taking photos of all the other butterflies in the backyard. 

Imagine my surprise (and joy!) when I downloaded my photos to my computer and discovered that the annoying piece of fluff (my over 40 eyes don't see like they used to!) was a fascinating little creature!  I had a pretty good idea as to what it was, so with a little bit of googling I determined that this was a pseudoscorpion! 

I am still researching this little arachnid, but for now, here are the...

Juicy Tidbits
  • Ranges between 2 - 8 mm in length
  • A predacious arachnid with venomous pedipalps to help it subdue its prey
  • Related to the scorpion... harmless to humans and pets
  • Beneficial to humans because they eat many other insects that are thought of as pests.  This includes clothes moth larvae, carpet beetle larvae, ants, small flies, mites and booklice to name a few.  And according to my photo, they perhaps eat butterflies as well
  • They live in leaf litter, under rocks, under bark and within decaying wood
  • They can end up in your home, but are harmless 
  • Are also know as a false scorpion or a book scorpion
Enough talk... let's get to the pics!

I am uncertain as to the fate of this butterfly.  Was the pseudoscorpion simply hitching a ride, or has it found itself a scrumptious (and rather large) meal?  If you know have any more information on this fascinating creature, please feel free to comment!

According to the good people at, the butterfly will not fall victim to this little beast.  The pseudoscorpion was indeed just hitchin' a ride!  Thanks for the info Ken Wolgemuth

  1. Very nice pictures! I was lucky enough to get a similar shot of a pseudoscorpion on a hackberry emporer butterfly. I wish mine was on a flower. =\ Here is a link to my picture.
