Three herbicide formulations, Roundup® Ready to Use Weed and Grass Killer, Bayer Advanced Southern Weed Killer for Lawns and Pure 20% Vinegar Solution were directly applied to eggs of four species of butterflies, Danaus plexippus, Papilio cresphontes, Papilio polyxenes and Papilio troilus. Roundup and Bayer Advanced containing 2,4-D, mecoprop-p and dicamba significantly reduced hatch success in all four species. Lethal and sublethal effects of these herbicides on the earthworm, Eisenia andrei, was also examined. Direct contact by E. andrei with a heavy dose of the herbicides applied to tops of soil 24 hours prior was lethal to earthworms. In a separate study, an amount equal to a light overspray was applied to soil on top of burrowing worms and no increase in mortality or reduction in reproduction was seen. However, we saw a trend of reduced reproduction coupled with increased adult weight in the light overspray with acetic acid that was significant and bears further study.
