Popis:	Poison hemlock, Conium maculatum L., a highly toxic, herbaceous, umbelliferous weed of Eurasian origin, was found to host many fewer species of phytophagous insects in southern California than other alien herbaceous weeds surveyed in the past. The most common insect associates were the “honeysuckle and parsnip aphid,” Hyadaphis foeniculi (Passerini), and the leafhopper, Euscelidius varigatus (Kirschbaum), both accidentally introduced European species. The other 18 insect species detected belonged to six orders and 13 families, and were represented by very few individuals in our collections. All 20 associated insect species were relatively unspecialized, polyphagous, ectophagous sap feeders or foliage feeders. The native “anise swallowtail” butterfly, Papilio zelicaon Lucas, apparently is in the process of transferring to poison hemlock as a food plant.
