Horned caterpillars
No, poinsettias (Euphorbia pulcherrima) are not poisonous to caterpillars.
Specifically, poinsettias are host plants to the Ello Sphinx moth (Erinnyis ello) caterpillar. The bright red colors that its modified leaves sport in December warn nature that it contains an irritating or poisonous substance within its body parts. Poinsettias are members of the Spurge family (Euphorbiaceae) of plants. Some spurge members are poisonous, others not. Poinsettias number among the family's irritating, non-poisonous members.
