| Neomegalotomus parvus (West.) behavior related to choosing crevices of pigeon pea, Cajanus cajan (L.) Millsp., pods to lay eggs were studied. Blocking antennae, tarsi, eyes, abdomen, or all structures simultaneously, did not affect the site of the pod (crevices) chosen to lay eggs. Oviposition occurred mainly in the afternoon. Most eggs were laid from 4 to 6 pm. Females moved antennae alternately up and down. Dabbing/antennation was accomplished, first with antennae and then with antennae and labial tip and the ovipositor was exposed and swept over the surface of the pod, leading to oviposition. Eggs were held together with an adhesive substance. Mechanoreceptors were observed on the ovipositor. |

| The phytophagous bug Neomegalotomus parvus (West.) feeds on pods and seeds of legumes. However, by the first time, in a laboratory colony, adults were found feeding on coespecific nymph and adult cadavers. Second instar nymphs, deprived of leguminous seeds, fed exclusively on died nymphs, reached the third instar. In the field, adults of N. parvus were found on animal carrions and feces, apparently feeding. Aggregations of adults were found on dog feces, as well. |
