Yesterday when we came home from the Regional Parks Botanic Garden we were pleasantly surprised to see a number of Pipevine Swallowtail Caterpillars. We had observed Pipevine Swallowtail butterflies a number of times over the past months check out our California Pipevine plants and lay eggs. We had even seen the eggs and some caterpillars earlier in the summer, but they disappeared. We don’t know if they were taken by predators who had gone into hiding. Today we saw the largest number to date. There was even Pipevine flower still in bloom.

Apparently there are tiny wasps that lay eggs on Monarch caterpillars and their larvae consume the caterpillars.
Jan bought special made tent to raise her monarchs and so far it has been successful.
