Ragweed pollen is a common allergen. A single plant may produce about a billion grains of pollen per season, and the pollen is transported on the wind. It causes about half of all cases of pollen-associated allergic reactions. (Hay fever). Common culprits are common ragweed (Ambrosia. artemisiifolia) and great ragweed (A. trifida). Goldenrod is usually flowering at the same time as ragweed so some people mistakenly believe they are allergic to golden rod when they are in fact reacting to ragweed. The great ragweed can grow to 15 ft or more and is found in wet areas, the common ragweed (not in the photo) has similar flowers but has dissected leaves (a bit like feathers), and is common at field edges. There are well over 20 different varieties of goldenrod, the commonest one is in the phtoto.
The monarch caterpillar on the milkweed, is quite similar to the black swallowtail caterpillar shown last week, but the monarch caterpillar has stripes while the swallowtail one has stripes and yellow spots, and is also on a different plant. On Wednesday we found a milkweed tiger moth caterpillar on a milkweed, it was somewhat similar to a monarch caterpillar but is very hairy.
The puffball I saw on August 15th has kept close to doubling its volume every day i.e. a 4” diameter puffball should have a diameter on following days of 5.04”, 6.36”,8.0”, 10.08”, and 12.7” and 16” if it kept on growing for that long. On Sunday it was just over 10” so right on the expected size but then it stopped growing.
On August 18th six hikers enjoyed a river walk at the falls, the water was very warm and no one had to go in water above their knees so it was a pleasant outing. Unfortunately the concession was not open so we could not enjoy their treats afterwards. Talking of treats only two hikers braved the rain on Tuesday, but 12 more hikers came afterwards to enjoy treats at the Worsells home.
At the railway trestle on the Bayfield river I saw two mink frogs, the first time I have ben able to photograph and positively identify this frog species, they are smaller than green and leopard frogs and their ‘dorsolateral lines do not extend the full length down the back.
