|Black Vine Weevil (Otiorhynchus sulcatus)|
So, here are the facts:
- Something I realised very quickly when I was researching these little creatures was that all the websites listed them as a 'garden pest' and rather than giving facts about them, it was about killing them.
- They are also known as the Black Vine Weevil for obvious reasons...
- ...These reasons include their colouring but (even though their name says so) there's nothing to do with vines that I can find.

- Back to their colouring, they are matt black. They also have fused wing covers meaning they cannot fly.
- They are very small, well Weevils are, aren't they... They have been recorded as 9mm long on average.
- The adults like to feed (at night) on the outer-edges of leaves and also the roots which causes death to a lot of the plants.
- They seem to go after plants that are grown in containers so make sure to protect your plants, they are a beautiful bug though and we shouldn't hate them.
- A humane way to protect your plants is to manually remove each bug at night time where they can be found feeding on the leaves but you have to use a dim torch as they are startled by bright light and will drop to the ground and scurry away.
- When I say protect, I don't mean all of them. Just the ones that they like. They particularly like soft fruits such as Strawberries and Raspberries.

- Females can reproduce Parthenogenetically. This is a rather long word and means only Females reproduce without Males. Basically, Males aren't needed...
- ...More on their lifecycle, after their larvae have become adults, they emerge between Spring and early Summer when a feeding frenzy begins. They then lay more eggs on a plant.
- Once the eggs have hatched, the larvae bury underground towards their root foods, they them moult several times over-winter before pupating at the start of Spring. The cycle restarts.
