Unknown insect eggs(?)
I found these on a plant in my backyard in Southern California. The plant is low and spindly and sits about two feet from a fountain that is always running. When I first took the pictures I didn’t notice the spider in the background. Yesterday, the two spiders were “face to face”. Now I notice that the one ate the other. Are they spider eggs? Did she eat him, like a black widow? What struck me about whatever these things are are their uniformity, abundance and metallic looking details.

Dear SoCal Soundguy,
These are Wax Scale Insects known as Barnacle Scales, Ceroplastes cirripediformis. You can confirm the ID on BugGuide
which indicates that it is a pest on quince and citrus in Florida. It is also reported from California. Images on BugGuide include specimens found on pomegranate, camellia and sage. We located a PDF online that pictures another similar looking species, Ceroplastes ceriferus, listed as the Indian Wax Scale. Soft Scale insects are plant sucking insects that can do major damage to plants if they get too plentiful. We wish you were able to provide us with the host plant name. It looks like it might be lantana, but we are not certain.

Daniel,
Thanks for your prompt, informative reply. You were interested in the
plant the finding came from. Not only did I send you a picture of the
plant but I did you one better: I included a picture of the plant tag
that the horticulture garden I bought it from (Huntington Gardens)
identified it with. The plant is Salvia Ulignosa.
I didn’t realize how many of these things were on the plant until I
pulled them off (they came off easily) or clipped high denisty clusters
like the branch shown. Then I burned them with a blow torch. I figured
that was the most definitive way to destroy them, lest they survive a
trip to a landfill and cause someone else a headache. …
