The gut microbiome plays an essential role in the health of many organisms, including insects. Here we report initial findings of bacteria present in the caterpillar midgut of the cabbage looper, Trichoplusia ni, grown in lab conditions on artificial diet and identified using biochemical tests. We identified one species previously reported as part of the gut microbiota of Trichoplusia ni and three species not previously reported. Our results support the need for multiple types of bacterial identification when looking at gut microbiomes, with the most confidence in identification being when multiple tests are in agreement.
