I noticed 2 of these on the bottom of a dead tree truck in some other plants when I saw this one in the first picture, it flew off and I was drawn to the other one that had this long tail (maybe 2?) dug into its hind end.. it took about a minute or so when the tail shot through ... something.. all of a sudden it had a tail as well.. it was weird.. in the second picture you see the bottom one being the one digging the tails in.. the top being the one with them out. I cant post the movie I\'ve got, But anyways was just curious what it was. Thanks everyone for your time.
