Greetings, Friends of the Prairie,

Just look at this little snake…I mean caterpillar. This is actually an Eastern Tiger Swallowtail (Papilio glaucus) with snake mimic eye markings. The caterpillar will even rear up a little like a snake when threatened. In a recent study, The New York Times reported that researchers studied the predator deterrent efficacy of this snake look-alike strategy by creating tasty plain green "pastry caterpillars". When placed on twigs, birds readily ate them. They then added eye spots on snake-like heads, and the birds tended to avoid them. No surprise really. Tiger Swallowtails are here because their caterpillars figured this out eons ago!

July and August are furious months for bumblebees (Bombus spp.) In the photo above they are feasting on Purple Prairie Clover (Dalea purpurea), a pioneer species claimed to prevent erosion, be great for making tea, and also to have medicinal properties. The Pawnee tribe used the stems to make brooms. The Bumblebees will move on to Bee Balm (Monarda fistulosa) and many other species seeking nectar and gathering pollen on their legs. They generally seek out one species at a time to forage
