We are so lucky to see lots of White-lined Sphinx Moths (Hyles lineata) in our yard every year.
(They feed on my Lantanas).

What I just found out this morning might explain why we see them. As it turns out, one of the host plants for their caterpillars is Mirabilis. The genus Mirabilis includes Desert Wishbone Bush which I have a lot of! I went out to see if I could find a caterpillar but nothing yet.

Note: I’m interested in caterpillars these days because I’m trying to include the native host plants in my flora guide sequel. Butterflies and Moths typically don’t lay their eggs on nectar plants so even if you see Butterflies in your yard, they may have hatched somewhere else.
