<br /> 30 <br />TABLE 2B: SPECIAL STATUS SPECIES THAT COULD OCCUR IN THE PROJECT VICINITY. <br />ANIMALS (adapted from CDFW 2023) <br />Species Listed as Threatened or Endangered under the State and/or Federal Endangered Species Acts <br />Common and scientific names Status <br />General habitat <br />description *Occurrence in the study area <br />Callippe silverspot butterfly <br />Speyeria callippe callippe <br />FE Occurs on grassy hills <br />surrounding the San <br />Francisco Bay that <br />support the host plant <br />Viola pedunculata. <br />Absent. Senior Associate <br />Entomologist Dr. Raymond White <br />surveyed for the host species viola <br />on March 13, 2015, within the <br />appropriate blooming period and <br />Viola pedunculata was not <br />observed. Therefore, as the host <br />plant for the Callippe silverspot <br />butterfly is absent from the site, <br />the Callippe silverspot butterfly is <br />also considered to be absent from <br />the site, although individuals may <br />fly over the site from time to time. <br />Crotch bumble bee CCE In California, inhabits <br />open grassland and <br />scrub habitats of the <br />southern 2/3 of <br />California. Historically <br />in, but largely extirpated <br />from the Central Valley. <br />Flight period for queens <br />is late February to late <br />October peaking in April <br />and July; flight period <br />for males and workers is <br />March through <br />September peaking in <br />early July. Constructs <br />nests underground in <br />animal burrows. <br />Overwintering sites are <br />likely in soft soils or in <br />debris or leaf litter. <br />Possible. The site is potentially <br />suitable for the Crotch bumble bee, <br />however, the presence of abundant <br />nectar sources has yet to be <br />assessed. The closest documented <br />observation of this species is more <br />than three miles from the site <br />(CDFW 2025).
