Crickets are NASTY little creatures. Surprisingly, at least for me, its pretty interesting to just sit and watch a large colony of crickets.
I had a VERY young gold dust day gecko that lost the last 1/4" of his tail. At first I thought it must be his cagemate (a VERY young crested gecko), as that lil guy had a very large head and it seemed feasible that he would be the culprit. Upon investigation though, I came to realize that crickets were to blame, mericlessly attacking the lil guy everytime he fell asleep.
Well, needless to say, crickets were minimized with that animal from then on.
Crickets have nasty lil mouth parts and are interested in everything from leafy green to fruit to meat to the bodies of dead fellow cage mates.
I can only imagine what a pain they would be, as a monitor, constantly attacking your sensitive areas (eyes, any wonds).
Then again, Ive also witnessed my monitor allowing a crayfish to move over its back, removing pieces of partially shed skin... before giving it the ol snap-munch combo... maybe the crickets serve a purpose other than food...
Some pics WOULD be awesome.
