Phytoseilius persimillus? OK, I'll bite since no one else has. What's
the common name?

Don, all,

I tend to lurk in the group but a favourite little animal got me typing. I
don't know if Phytoseilius has a common name, does it need one ?

If it is the beastie that I am thinking of it is a very effective predator
of red spider mites. It was said that it cannot deal with a heavy
infestation, this is not totally true, in my experience.

Yes they of course are more quickly seen to work against low infestations
and low mite densities but you need to remember that it is not a spray
but a predator. There are lots of factors in its effectiveness.

It eats the mites [anyone opens up a thread on how it sucks them not eats
outbreed the predator, at cooler temperatures. However at higher temps (
I think ? circa 75F) this ceases to be true and then you have a marvellous
situation when you have "limitless" food for the predator to eat, and
predator outbreeds the prey species - that is when they can mop up pretty

Persimillis are preditory mites that really do a great job cleaning out
spider mites -- eggs and all!! The bug store has them. -----bugstore.com
