Do Spiders Release Pheromones When Killed?
WouterIf you think spiders release pheromones when killed, you may be wrong. Although some species do, others do not.
The reason behind this is unclear. One possibility is that these chemicals are used as a warning to other insects. The pheromones may also serve as a signal line to warn other animals of the presence of a predator.
Another theory is that these chemicals were developed in an intermediate stage of spider evolution. During this time, they became useful for a variety of activities. For example, the silk they produced was used to manufacture egg sacs and other devices for prey capture.
However, some arachnologists have doubts about this theory. They believe that spiders are more individualistic than bees. This means that they spend most of their lives in isolated groups. This makes it difficult to study how they respond to vibrations.
The pheromones that spiders use to warn other insects may be the same chemical that attracts other bees. Bees need to find and alarm other bees to ensure their survival. The female bees that do not produce pheromones are usually less aggressive. This means that they are not the most attractive to other bees.
Many people confuse the pheromones that spiders release when killed with the bee pheromones. It is important to keep these differences in mind when you are deciding to keep or kill a spider.
The pheromones released by dead spiders do not attract other spiders. But they may indirectly attract insects that eat the dead spider. For this reason, it is recommended to leave the spider alone.
