I have heard that the Green Lacewings are born in or under the bark of a California Sycamore Tree.  
 
Is this true?

In the photo of spider making a meal of the green lacewing, was curious to know if someone could ID species of the spider. Thx JT

What would be some good plants to put in the garden to attract lacewings? Do they favor laying eggs on something in particular?  
 
thanks!

John, the spider, as identified by senior museum scientist Steve Heydon of the Bohart Museum of Entomology is a Western spotted orb weaver, Neoscona oaxacensis.  
 
DeeDee and Carmen, UC Davis entomologist Jay Rosenheim says:  
"Lacewings lay their eggs all over the place (delicate little oval eggs, held on the ends of long stalks, often), especially relatively close to prey (aphids, or others). If the sycamores are hosting lots of aphids, that could explain the presence of eggs. But the eggs are all over."  
 
"I think there are some spray-on foods (including yeast hydrolysate) that are supposed to attract adult lacewings, but whether they are really available commercially here in the states? I just don’t know."
