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

After 3 years of trial & error, we finally have a means to germinate seeds and study them in natural populations and common gardens

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.

Mojave Desert Sidewinder - Crotalus cerastes cerastes

#herps
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 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

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
