Insect Egg Mass

Insect Egg Mass
Cobble Hill, British Columbia, Canada
May 30, 2008
This egg mass was on my window

Moved from Unidentified Eggs.


Individual eggs
I think that on the full-sized image I can just barely make out a pattern of radiating ridges on some of the eggs, which seems noctuid-like.

Pentatomidae (Stink Bugs)?
Pretty sure these are Pentatomidae eggs.

These look spherical -
while we think of Pentatomid eggs as cylindrical

Pentatomidae seem to have some type of "escape hatch", which I can't see on these.

Spherical eggs laid in a cluster on a window are most likely laid by a moth that was attracted to the light. I've never seen a hexagonal cluster like that before though.

This website says that noctuid moth eggs are often laid in neat diagonal rows, so I think that would be a good bet. I was already thinking they might be from a noctuid based on the apparent shape (compare with the illustration on the linked website), but I would need a more close-up image to be sure I wasn't imagining that.
