Yes, this is Synema globosum. Crab spiders will actively catch and feed on many different insects and other invertebrates. To date there has been no proof of an established population of the spider, and records have either certainly or may have been the result of casual imports e.g. in flowers etc. There is good reason though to expect it to become established, since it is very widespread in Europe.
The reason your photo did not show in the post was that you managed to double insert it soemhow. You can insert a picture simpling by clicking once on the mini photo shown above the text entry. I have sorted that out now.
