Author Dr Helen Roy said: "Wales is lucky in the sense that every ladybird found in other parts of Britain live there, but Wales is unique because it is the only place in the UK where the five-spot ladybird is found.
Especially in the areas of the River Severn because it could pose a danger to the five-spot species.
The UK five-spot ladybird is only found in Wales where it likes the damp shingle of the River Severn
Over the past two weeks injections of HOA-800 have been concentrated on the five-spot
test of oil wells on the Olmos lease.
For example, a two-spot is two numbers; a five-spot, five numbers.
Game participants also can try to match two numbers in a three-spot; two or three numbers in a four-spot; or three or four numbers in a five-spot.
Five-spot players who match all five numbers win the most - usually in the $200 range.
