Wildflower of the Month/September-Ironweed

September brings us the underrated Ironweed. I always look forward to their purple splender. This tall wildflower is a butterfly magnet.
The New York Ironweed (Vernonia noveboracensis) is common, statewide in moist bottomland fields. Tall Ironweed (Vernonia altissima) is common in moist areas west of the Alleghenies. One other ironweed can be found east of the mountains. The Broad-leaved Ironweed (Vernonia glauca); though rare, may be found in some locations to the East.
The purple flowers of these species are a host of numerous butterfly, moth,wasps, bees, flies, bugs and other insects. A pure field of Ironweed in the perfect light is a sight to see.

Yellow Ironweed (Verbesina alternifolia) is the common yellow flower of roadsides and fields. This tall yellow flower; while is by no means  spectacular or rare, is an important host for many species.

While on your travels through the fields and forests of September, do not forget to observe the weeds. You never know what you will find there.

Butterfly of the Month/August-Eastern Tiger Swallowtail


The Eastern Tiger Swallowtail (Papilio glaucus) is probably the most noticable butterfly of our region, during the month of August. You may not know that the female is more often black as opposed to yellow. This is one of natures' ways of mimicing. The black form females resemble the Pipevine Swallowtail and are less likely to become bird food.

The most common larval host species is Yellow-poplar and black cherry.Although, there is usually a caterpillar to be found on the spicebushes in my yard.

These large and plentiful butterflies will be found feeding upon the flowers of Joe-pye Weed, Ironweed, milkweeds and thistles. Therefore, they can be found at nearly every location.
