Predation

IMG_6892 crop red

Crab spiders have the ability to change color to match that of the flower they’re on. In this case, it’s among wingstem flowers. This is a female crab spider. Males are much smaller.

Her prey looks like a tachina fly.

Here’s another example of predation:

I blogged this chrysalis earlier this summer. It was attached to the side of our garbage container.

It belonged to a tawny emperor butterfly.

A couple of weeks later another chrysalis was attached to the side of the container. I knew it was parasitized when it started turning dark.

Then came even another predator.

A Tachina Fly

These tachina flies were numerous

back when the butterflyweed was blooming the end of June.

Three of these tachina (Trichopoda pennipes) flies also stayed in the area.

This half-inch one mates near flowers and attaches its eggs to medium-sized and large true bugs. Its larvae enter the host to feed. Some pupate in the host and emerge in the spring.  Other tachina species pupate in the soil emerge in the summer or fall.
