As of mid-April 2008 it appears that alfalfa butterflies have successfully overwintered in good numbers. We experienced huge numbers of the yellow or white butterflies last fall and alfalfa growers should keep an eye out for problems this spring and summer. There is typically a two week delay between the time the butterflies are in the field and larval damage. You can find more information on alfalfa caterpillars at the High Plains IPM web site. |
