Your bees can reproduce quickly enough to keep up with incidental foraging losses to spiders.

I’m so glad! Spiders are fascinating creatures. Here is a short excerpt from the Encyclopedia Britannica: “Males in a few species locate a female and unceremoniously run to her and mate. In most species, however, elaborate courtship patterns have evolved, probably to protect the male from being mistaken for prey. The male of the orb weaver family (Araneidae) and some others court by rhythmically plucking the threads of a web. After the female approaches, he pats and strokes her before mating. When male wolf spiders or jumping spiders see a female, they wave the pedipalps, conveying a visual message characteristic of the species. An appropriate response… Read more »

There was a post right here on SpiderID not long ago that inspired me to do some research on spider mating rituals. Here’s the link:
