Here in Shiga Prefecture some wildflowers continue to bloom well into November. They attract a variety of flying insects, including butterflies, moths, bees, hoverflies, and wasps.
On November 3, 2018, quite a few insects were feeding along an irrigation canal near rice and soybean fields near my home.
Few insects visit tiny flowers such as henbit dead-nettle (ホトケノザ).
Tall goldenrod (セイタカアワダチソウ) grows beside fields and along rivers and ponds. Many species of insects can be seen on goldenrod flowers.
On November 5th, 6th, and 8th, I saw insects on tall goldenrod near the irrigation canal in Tsuji, the riverbank near the tennis courts in Yasugawa Athletic Park (野洲川運動公園), and along Oyamakawa (大山川) in Yasu City.
On November 16th a potter wasp was on tall goldenrod at the reservior near Ono Ramp in Ritto City.
Other flowering weeds compete with tall goldenrod. Bidens pilosa (beggar’s tick, コセンダングサ) yellow disc florets continue to attract bees and other small butterflies after the white ray florets fall off.
Bidens pilosa fruits come off easily and attach themselves to clothing.
Other flowers have continued to bloom and attract insects in November.
After mid-November larger insects such as butterflies are becoming rare.
