Return to Life Cycle Studies of Lower Rio Grande Valley Butterflies

On 4/3/2007, I observed a Lyside Sulphur - Kricongonia lyside lay eggs on our Soapbush  or Guayacan - Guaiacum angustifolium, in our backyard.  I collected a twig with eggs for rearing, and 18 days later the Lyside Sulphur emerged and was released.

Soapbush or Guayacan - Guaiacum angustifolium, the host plant of the Lyside Sulphur - Kricogonia lyside, is common but generally limited to South Texas, thus generally limiting the Lyside Sulphur to South Texas, also.
