Meet the pea aphid (Acyrthosiphon pisum)! The pea aphid is one of the thousands of species of aphids that pester plants. Aphids are like “plant mosquitoes” because they drink the phloem (the nutrient-rich sap) of plants with needle like mouth parts. Although one aphid by herself doesn’t cause much damage, aphids can transmit harmful viruses between plants. Aphids also clone themselves! A lone female aphid can produce hundreds of genetically identical offspring without a mate. Therefore, one aphid in a greenhouse or crop field could be the start of an invasion. In this photo, I am using an eyeshadow brush to pick up live aphids and move them onto plants as part of an experiment to measure the plants’ defence response to aphid infestation.

The return of the Black Cutworm. Part II. Its 12 eyes strike fear in corn. And would in you too if said Cutworm were 6 feet tall (or long). This one is worth blowing up (photographically speaking). Disconcerting topography here. What are all those things we are looking at in this picture? We are so confident in our superiority, nay our nobility, that caterpillars are really beneath us. But I bet you have no clue why they have those scattered hairs on their body, why they are stout, why they are so utterly symmetrical, why their bases appear to be bearing raceways, and what happens to them when they pupate. Actually, neither do I.
