Stink Bug Eggs – 3 batches
On May 19, 2012, Sandy found this patch of eggs on a lilac leaf, so she gave it to me to hatch out.
Which they did, exactly a week later (May 26).
See for example these eggs, that Sandy found on a plum-tree leaf on June 14, 2012.
They’re obviously a different stinkbug, with that mirrorlike sheen and the much longer fringes around the seam where they will pop open. That longer fringe is generally characteristic of the genus Podisus. Yet what comes out of them just a few days later (June 19) looks pretty similar to the previous batch.
These were very close to hatching when found, the brown spots are the eyes and similar features of the soon-to-hatch nymphs.
And those also turned out to be stink bugs.
The first and third batches look an awful lot alike, and are probably closely related, although the eggs were laid about a month apart so I kind of suspect they aren’t the same species. Another point is that they were laid on wildly divergent plants – lilacs are not much like rosemary, both of them have significant chemical defenses against being eaten, and I’d be inclined to doubt that a herbivorous insect would be equally likely to suck juices from both of them.
Although, there is a pretty good chance that these were actually predatory stink bugs, which we evidently have a significant number of. As I plan on showing next time. And in that case, the plant that the eggs are laid on would be completely beside the point and totally irrelevant.
