A New Yorker in Oslo: Iberia slugs

The less pleasant underside of nature

There are a lot of spider webs in the garden this year, many more than I remember from last year. There must be a lot of insects out and about, judging by the number and placement of the webs. But I cannot remember that spiders spun webs in the raspberry bushes before. I came upon one of them yesterday, and noticed that there was a honeybee trapped in the web; the spider was close by. I decided to try to free the bee, but I took a photo of the spider and the bee before I wrecked the web trying to free the bee. As it turned out, the bee was stone dead, and nothing I tried could revive it. I didn't feel too bad about destroying the web because I felt it was for a good cause. I am partial to honeybees because they are hard workers and they don't bother you if you don't bother them. The same is true of spiders, and I usually don't destroy their webs or bother them in any way. So this was an unusual situation.

While I was digging up potatoes yesterday, I came across a pile of what looked like small translucent pearls. I've seen them once before in the strawberry patch, a few years ago. They are rather pretty, but the slimy underside is that these are slug eggs, and not just any slug, but the brown Iberia slug (Spanish slug) that is a major pest in many gardens. From my online searches, I found that slug eggs are translucent when newly-laid and become more opaque over time. I also read that young adult slugs lay fewer eggs than older adult slugs. Our community garden board encourages us to get rid of them, so I did. I'm sure there are other piles of eggs placed around the garden; this particular pile was almost in plain view, which is a bit odd. In one of the eggs at the bottom left of the photo I took you can see a brownish line; I wonder if that is a baby slug forming.

There is an underside to nature that isn't always pretty or pleasant. That underside is part of the entire picture--the positive and the negative, the light and the dark, the beauty and the ugliness, the predators and the prey, the plants and the slugs that eat them. That dichotomy is part of nature and part of life.
