The 22% drop in butterflies in 2011 is thought to be the result of an unusually cold summer and the ongoing deterioration of suitable habitat for the insects, wildlife charity Butterfly Conservation said.
The "wider countryside butterfly survey" involves counting butterflies in more than 700 random one kilometre squares across the UK landscape.
A garden favourite, the small tortoiseshell, did particularly badly last year, with fewer than one butterfly seen per kilometre walked by recorders.
Butterfly Conservation said the low numbers were a cause for concern as less than a decade ago the small tortoiseshell was likely to be seen in almost every garden and flower-rich spot.
The common blue also struggled, with the butterfly spotted in only a third of the sites surveyed, compared to more than half in 2010.
And the once-widespread wall butterfly was largely absent from central England, the study revealed.
The meadow brown was the most widespread and abundant butterfly, spotted in 80% of surveys.
Overall, recorders saw an average of 47 butterflies from seven species per survey made last July and August.
The results are a 22% decrease on the 2010 figures and 41% down on 2009, the first year of the scheme, when recorders spotted an average of 80 butterflies and eight species.
The survey's co-ordinator Dr Zoe Randle said: "The new survey is proving vital in getting better information on how our common butterflies are faring across the countryside as a whole.
"The gloomy results show we need to step up efforts to rebuild a better countryside for butterflies."
The survey is run by Butterfly Conservation, the British Trust for Ornithology and the Centre for Ecology and Hydrology (CEH) as part of the UK butterfly monitoring scheme.
Kate Risely, of the BTO, said: "It is important to carefully monitor the numbers of our wider countryside butterfly species in order to detect potential threats to their populations.
"Results from the upcoming 2012 survey and in years to come will show whether these declines are sustained."
