The flowering plants (angiosperms), also known as Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 416 families, approx. 13,164 known genera and a total of ca 295,383 known species (Wikipedia). The angiosperms diverged from the gymnosperms in the Triassic period when dinosaurs were first evolving about 240 million years ago. Most of our food plants are angiosperms and many require the help of pollinators to produce fruit such as pumpkins, squash, tomatoes, corn, beans and just about all the fruits and nuts. We tend to take them for granted but without them we would be virtually unable to produce these. Here at Breakneck Hill Farm, the farmer before me, Ray Davis, because of his orchards and honey bees recognized the value of providing habitat and food for these insects and planted Linden (American Basswood) and Spanish Chestnut trees. They are now fully grown and from mid-June to mid July the trees are literally buzzing with thousands of bees when you walk beneath them.
I have also planted small gardens with late season flowers that will help to feed not only the pollinators but also the beneficial insects like parasitic wasps which will keep pests in check.
My kale got hit pretty hard by the aphids this late season. Unfortunately here the lady beetle has gotten on the job a little on the late side. By identifying the problem early I might have been able to suppress the population with something like Neem oil enough to allow some of the kale to survive. They certainly seemed to prefer the Red Russian kale over the curly.
This monster is a Tomato Hornworm, unfortunate for him/her they are covered in the cocoons of a braconid parasitic wasp. They will eat this destructive caterpillar from the inside out and then mature and go find another. This is how we use nature to do our dirty work.
