Flea beetle (Order Coleoptera, Tribe Alticini). The name "flea beetle" refers to small, jumping beetles from the family Chrysomelidae (a leaf beetle family). Their ability to jump comes from their large hind legs. Flea beetles have a reputation as a human pest because they tend to attack agricultural crops. Like all beetles, flea beetles undergo complete metamorphosis.
Plant bugs (Order Hemiptera, Family Miridae, Genus Phytocoris?). Plant bugs are "true bugs," meaning they don't undergo metamorphosis at all. They are known as agricultural pests because they have sucking and piercing mouthparts which extract sap from plant leaves.
1 worker ant (Order Hymenoptera, Family Formicidae, Genus Neivamyrmex?). Ants, which develop through complete metamorphosis, form colonies that function in a caste system. They primarily differentiate into queens and workers. Gene expression and nutrition in the larva stage further specialize ants into different castes. Ants in a colony communicate with each other using pheromones and smells.
Horse fly? (Order Diptera, Family Tabanidae?) The ID in this fly is a little questionable. I haven't found a fly species with the same color underbelly as the one here. It is the largest of the flies I collected. Flies undergo complete metamorphosis and the larva stage can actually be the dominant stage. While in the larva stage, flies are known as maggots. Humans actually utilize maggots in many different situations. In the summer flies reproduce a lot, which can result in maggot…
I spent a lot of time trying to ID this bug. Sadly I didn't find it in time to send it to Liz's entomologist friend. I believe it's some form of beetle? (Order Coleoptera). The structure of the legs and the antennae seem beetle-like to me. However, the markings on the abdomen confuse me, I don't see much like it in the beetle family. Maybe it's an immature form of another bug that isn't documented in our field guide?
