Scaldweed, Cuscuta gronovii, a native annual non-photosynthetic #parasitic #plant - haustoria instead of roots; shares #herbivores with its host plants (you are what you eat) - but a #flowering plant nonetheless. Most plant communities have several distantly related species of parasitic angiosperms

I've been seeing more of the Jerusalem artichoke Helianthus tuberosus around the great lakes region. This is from the sandy east shores of Lake Ontario. Said to be native, I wonder if it's being planted more and spreading?

The American searocket,
Cakile edentula, a sand loving semi-succulent #Brassicaceae. I knew this plant from the west coast; here on the shores of lake Ontario. Fruits have two-parts, one that breaks off and floats for water dispersal. immature silliques are edible, like radish pods

The elegant track of a baby sidewinder zigs and zags up a sand dune. The sidewinder is visible at the end of the track at the top.

The elegant track of a baby sidewinder zigs and zags up a sand dune. The sidewinder is visible at the end of the track at the top.

A baby sidewinder's tracks tell the story of the last few minutes.

First, an elegant change in direction and in sidewinding handedness, like the jibe of a sailboat. Then a startled squiggle as it realizes it's being followed.

And next to the #orchid, pondside, abundant greater fringed gentians, Gentianopsis crinita, a spectacular biennial; reproductive parts heavily attacked by a plume moth. After 3 years of trial & error, we finally have a means to germinate seeds and study them in natural populations and common gardens

Kleinia pendula (formerly in #Senecio) - the inchworm plant from NE Africa. A rayless creeping #succulent #aster (w/ red flowers)... here with the aphid, #Aphis nerrii, in Ithaca; I usually think of A. nerrii as a specialist on #Apocynaceae (but there are several reports on asters) #herbivory

Gray white fuzzy moth on a human hand

A male large tolype #moth (or velleda lappet moth), Tolype velleda, an eastern north american tree leaf feeder (as caterpillar). Adults do not have mouth parts - no feeding, just flying and mating. Note one feathery antenna: high surface area to pick up on female-produced pheromones

Beech drops, Epifagus virginiana (Orobanchaceae), non-photosynthetic & #parasitic, feeds from beech tree roots. Flowering in an old-growth pine forest. Has a ridiculous life-cycle, including both cleistogamous & chasmogamous #flowers, possible #ant #pollination, etc. wikipedia.org/wiki/Epifagus

Tachinid #parasitoid emerging from #monarch #butterfly chrysalis... The larva was never exposed, but field collected leaves were fed to the caterpillar. Many tachinids lay their eggs on leaves, only to be consumed by caterpillars, later consuming the caterpillars from the inside out

Say's mantidfly (Dicromantispa sayi), a lacewing relative that looks as its name suggests like a chimera between a fly and a praying mantis, here clinging to the storm door with the garden in reflection behind it. Downers Grove this morning, sighted by @art_bumble.

Pokeweed, Phytolacca americana -- A perennial favorite of late summer. I don't love it less now that I know that the declaration of Independence was not written in its ink. It's berries were used in the colonial era for ink and dyes, we should get back to that!
