The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Dendrobates auratus
Dendrobates auratus
(Green and Black Poison Dart Frog)

Copyright Info
Dendrobates auratus (Girard, 1855)

Common name: Green and Black Poison Dart Frog

Taxonomy: available through www.itis.govITIS logo

Identification: Dendrobates auratus is a small, dark dendrobatid (poison frog), lacking webbing on its feet, with a SVL (snout-vent length) of 25-42 mm (1-1.7 in) (Silverstone, 1975; Zimmermann, 1986; Norman, 1998).  Color varies considerably and is usually a black or dark brown, with blotches, spots or bands of color, variable in size and exhibiting varying shades of green, tan, gold, yellow, blue, or blue-white (Silverstone, 1975; Savage and Villa R., 1986; Mattison, 1987a; Walls, 1994; Pröhl, 1997).  Most Hawaiian specimens tend to be patterned green or green-gold, but some are blue-white (Walls, 1994; McKeown, 1996).  The male's call is a slurred, high, musical "cheez-cheez-cheez" (Silverstone, 1975; Norman, 1998).  Adults of this species have been illustrated by numerous authors (Cochran and Goin, 1970; Silverstone, 1975; McKeown, 1978, 1996; Wells, 1978; Zimmerman[n], 1979; Frieberg and Walls, 1984; Mattison, 1987a; Walls, 1994; Lamar, 1997; Pröhl, 1997; Renjifo, [1997]; Norman, 1998; Vivarium Staff, 1998; Pough et al., 2001).  Additionally, the tadpoles of D. auratus have been illustrated by Silverstone (1975), McKeown (1978, 1996), and Walls (1994); the poison skin glands have been illustrated by Myers and Daly (1983).  There are no frogs similar to D. auratus established in Hawaii, but see the accounts titled "Dendrobates leucomelas Steindachner, 1864" and "Dendrobates sp. Wagler, 1830" on this website.

Size: snout-vent length of 25-42 mm

Native Range: The green and black dart-poison frog is indigenous to the Central American countries of Costa Rica, Panama, southern Nicaragua, and northern Colombia (Silverstone, 1975; Frost, 1985; Savage and Villa R., 1986; Walls, 1994; Pröhl, 1997; Renjifo, [1997]; Norman, 1998; Campbell, 1999; Duellman, 1999).

Means of Introduction: The green and black dart-poison frog was intentionally introduced to the upper Manoa Valley on Oahu, in 1932, for mosquito control (McKeown, 1978, 1996; Vivarium Staff, 1998).  The means of introduction on Maui is not known.

Status: These dart-poison frogs are established in Oahu (Oliver and Shaw, 1953; McKeown, 1978, 1996; Smith and Kohler, 1978; Frost, 1985; Walls, 1994, 1998), but are not listed in Frost (2000) or Crother et al. (2001).  Until recently there have been no known dendrobatids on Maui, Hawaii (McKeown, 1996), but this latest discovery seems to indicate they are established (Duerr and Hirayama, 2002).

Impact of Introduction: Unknown; however, their primarily insectivorous diet could impact native endemic species, if this has not happened already.  Hawaii has no indigenous frogs (McKeown, 1996).

Remarks: The green and black dart-poison frog has been the subject of a variety of taxonomic studies and summaries (Silverstone, 1975; Myers and Daly, 1983; Frost, 1985; Zimmermann and Zimmermann, 1988; Caldwell, 1996; Summers et al., 1999).  Dendrobates auratus is primarily a nonaquatic, diurnal frog; active during the day in vegetated, moist habitats (McKeown, 1996).  In their native range, D. auratus eats primarily ants (myrmecophagy) and mites (Caldwell, 1996).  The alkaloid toxin in their poison skin glands apparently is derived from the ants that are ingested (Caldwell, 1996).  Males are polygynous during the breeding season; however, the females compete for and guard their mates from other females (Summers, 1989, 1990; Crump, 1995), and may even destroy the eggs of competitors (Summers, 1989).  Females lay terrestrial eggs in a moist, sheltered area; the eggs are fertilized then protected by the father (Wells, 1978, 1981; Zimmerman[n], 1979; Weygoldt, 1987; Summers, 1990; Walls, 1994; Crump, 1995; McKeown, 1996; Pröhl, 1997; Summers et al., 1999).  When the tadpoles hatch the father transports them on his back to small pools of water (Eaton, 1941; Wells, 1978, 1981; Weygoldt, 1987; Zimmermann and Zimmermann, 1988; Summers, 1990; Crump, 1995); in Hawaii, these could be pools formed in rainwater-filled debris or depressions in lava rock (McKeown, 1996).  The tadpoles are omnivorous (McKeown, 1996).  In Hawaii, the introduced Gold Dust Day Gecko (Phelsuma laticauda) has been observed to consume these tadpoles (Chan et al. 2007).  Dendrobates auratus is a popular species; kept and bred by hobbyists worldwide (Zimmerman[n], 1979; Mattison, 1987a, b; Zimmermann, 1986; Walls, 1994; Davies and Davies, 1997).  The Hawaiian populations on Oahu may be the principle source of stock for the commercial pet trade (Walls, 1994, 1998).
