|Silverfish - actual size|
Throughout time, humans have lived in close proximity to insects. Just today I read that in several French cities there has been an explosion in the bed bug population while over in Africa mosquitoes continues to spread death as they are the prime carriers of malaria. Fortunately, most insects are benign and hardly trouble us at all. In fact, they mainly benefit our lives.
Here in northern England, insects are most obvious in the summertime. Out in our suburban garden, insects flit between plants or crawl in the grass. There are thousands of them. Long ago, Jimmie Rodgers recorded a song called "An English Country Garden" in which he asked: "How many insects come here and go/ Through our English country garden? " Well for the life of me Jimmie I cannot say but a hell of a lot.
Sometimes, I visit our downstairs toilet before I go to bed and very often I spot an insect on our vinyl flooring. I have only ever seen one on its own and I have never seen one in the daytime.
It scuttles about and obviously does not appreciate the electric light. See the image at the top - it is a silverfish and it loves dark, damp places like benighted bathrooms. I guess that if we have one silverfish there must be more but I have never seen them. If you get an infestation they can cause minor damage but I think that our silverfish must be living off dead skin particles and dandruff.
You are probably curious about how silverfish reproduce so I have undertaken extensive research (read the Wikipedia page) to satisfy your curiosity...
