There are 24 of them, each ovoid, 1mm long and attached to the switch's frame by suction cups connected by tubes. They are secured to the base and couldn't be brushed off with a stick. Found them in East of India.
The ovoid heads have reduced in number (17) and have turned brownish (10.04.2017). The number of ovoid heads are 11 now and two of them have a black spot at the proximal end (could be the eye spots of developing embryos) (13.04.2017). The bunch has 4 of them now (24.04.2017).
Research & Question:
Assuming those are eggs (resemble those of Green lacewing and with the changes observed it is evident), what group of arthropods have such stalked eggs other than Green lacewing?
