You need to have found all 5 caches in the nearby "Catching the Bug series" in order to find this cache.
The cache is not at the listed coordinates - don't go there as its the middle of a pond!
Once you have all 5 bonus numbers (listed on the log books in each cache), use the following formula to find the cache coordinates. You then need to add the location as a new waypoint on your GPS device/smartphone.
N51 11.BAD W000 09.(C+E)(B-A)(A+C+E)
The Bug eater will not let you sign the log easily - he has a final challenge in store...
You can check the answer to see if you have got the right coordinates using the geochecker link below 
Catching the Bug - An Introductory Series
An introductory series of caches intended to :-
- Provide some easy but interesting geocaches in a beautiful and off road location
- Appeal to the young (and young at heart!) via gratuitous help from members of the insect world
- Encourage those new to geocaching to go out and find more, hence "catching the (geocaching) bug" :)
