Phytophagy



Dear Recipients,

This week features two types of beetle that feed on plant (phytophagy). The first belongs to the family Chrysomelidae, which contains species that feed chiefly on foliage and flowers. This group contains many pest species such as the Colorado Potato Beetle and Flea Beetles. The second beetle is a weevil (Curculionidae) which also contains may pest species. However, unlike most chrysomelid larvae, weevil larvae typically burrow into the host plant or seed on which they are feeding. As can be seen in this specimen, most weevils have the mouthparts and antennae at the end of a snout.
