granddaddy longlegs-good or bad, orchid-wise?

[VickiC]

First of all, my camera is on the blink, so I'm unable to post a picture....memory card failure (although a photo might not have been necessary this time). ???

There are several granddaddy longlegs (Pholcus phalangioides, according to the Internet) in my greenhouse this season and I have been wondering if they are beneficial or detrimental to orchids. My husband says that since they are carnivorous, he assumes they are helpful by catching insects that would be harmful to my plants, but that he didn't know about plant tissue. Just this morning, I closely watched one crawling around on a plant - mostly on a catt. new growth - and it looked as if it's mouthpart was very close or on the growth. (There was not another insect on that new growth, by the way)

Would someone please advise me if I should or should not 'remove' them from my plants?

Thanks in advance,
Vicki
