Solved Spider on dahlia, what is it.

I have only seen one so far and left in situ. Should I send it on its way or just leave?
It is a bright green color and on the petals not the stalk or leaves.

 

Its just a spider.
Spiders are in general good, as they eat pests.
leave it, it wont do any harm.

 

Hey! We cant kill everything even though I hate spiders
Yes, just let it be

 

Yes, they are your friends eating all the nasty little bugs, I'm happy to let them stay in the greenhouse and even in the house , other than the bedroom.

I always call them Fred, seems much friendlier....

 

OK point taken, I will let it be.

 

Great photo. Do you know the name of it, (Fred excluded)? Strange that so many of us shudder when confronted with a spider, considering what big tough individuals we are.
!!!
Yes the spider comes in all sizes and can be our friends in the garden etc, however most spiders can actually give you bite, and if you are so unfortunate then it is advisable to get medical attention however slight it might seem.

For instance there is an ever increasing number of bugs etc that come into the country from abroard, especially with plant imports and fruit. There are websites showing loads of spiders whereby you might be able to identify your one. Scientist at the Natural History Museum London will willingly identify and provide you with plenty of info.

Hope this is useful.
