This is a Trooshti -- Star Wars insect from Tatooine. It's look like UCS model, but I think it isn't UCS. You can see this bug in comic "Queen Amidala". It has a adjustable legs, head, wings and tentacles. There are also a battery (which is very important in this comic) and stand with a place for minifig -- Padme Neberie, or Jar-Jar Binks and UCS style label.
