        While many of you were recording your first butterfly sighting of 
     the year, some of us folks here in southern California have already 
     completed the year's first July 4th Count at Joshua Tree National 
     Park. The count is run early because Joshua Tree straddles the Mojave 
     and Colorado deserts and a count at the more traditional June-July 
     time would find very few butterflies and overheated counters. The 
     following is the list of 30 species found and numbers counted as 
     totaled by compiler Marilyn Lutz:

     beckerii, 5; Spring White, Pontia sisymbrii, 1; Checkered White,
