All's Right with the World...


   

...when Guests find Hosts!    

Clouded Crimson Moth caterpillars need plants in the Primrose family.

Here is a member of that family, growing in a road ditch. 

Gaura mollis, aka Velvetweed, is
a native annual/biennial that can grow
over six feet tall.


And here is its little "guest!"

Dogbane moths look for--guess what--Dogbane!

Not all guests are well mannered.   The caterpillars of Saucrobotys futilalis, the Dogbane Saucrobotys, can eat their host out of house and home:

And of course famously, Monarch caterpillars need milkweed:

Many insects are generalists and can live off of numerous species of plants.   But some are specialists, like the ones above.   If their host plants disappear, so do they.   And if insects disappear, so do birds, flowers, fruits, vegetables, and eventually--us.  Therefore, it's a special thrill to see  insects finding the plants they need.   It means in some ways anyway, all's right with the world!   

All can share in this thrill!  Just plant native plants.  Whether it's milkweed in a window box four stories up, a 1/8 acre plot at a church or school, or thousands of acres of former cropground next to a national park, it will all help to set the world to rights!
