Twins!

  About noontime, Mark and I headed over to our daughter and son-in-law's place for a Father's Day cookout.  Robbie was grilling hamburgers which was the perfect meal to have for his father-in-law.  You just cannot go wrong with a burger for a guy!  After we ate, Elizabeth and I took our usual stroll about the place.  We checked her gardens, the spot she chose for a shoofly and the trimming job that Robbie did on the oak tree.  All looked well kempt.  

  She then showed me her satsuma and grapefruit trees. "Caterpillars ate my satsuma tree." she bemoaned but then looking at the bright side "But look!  I have twins!  Sure enough on the trunk of the little tree, two fat chrysalides were suspended by thin silk.  Elizabeth informed me that there were more caterpillars on the little trees but she smashed them not realizing just what they were.  When I told her that these caterpillars will change into Great Swallowtails, she was all for leaving them.  So the bush got pruned until it was nigh on devoid of leaves.  The "Orange Dogs" were fat and happy!  Twins!  

  The Giant Swallowtail butterfly lays her eggs on citrus trees if available, hence the name Orange Dog caterpillar.  These caterpillars bear a striking resemblance to fresh bird poop.  This is not their only defense, however.  If threatened, bright red "horns" called osmeterium emerge from their head and emit an odor that is quite convincing of the bird poop camouflage.  Not too many critters want to go around eating stinky bird poop so the caterpillars munch away unmolested.

  While the menfolk decided to do a bit of mechanical work on the lawnmower, Elizabeth and I had a grand time exploring her place a bit more.  All in all, it was a delightful way to spend the afternoon!
