Eleodes goryi (Globular Darkling Beetle)

Eleodes goryi

(Globular Darkling Beetle)

Globular Darkling Beetles may be one of the most adorably shaped tenebrionids that the United States has to offer. The adult females exhibit extremely bulbous abdomens, which aren't just round, but nearly circular! Males are notably more slender. Larvae are unusually dark for an Eleodes sp. and more closely resemble something like Zophobas atratus in coloration. Eleodes goryi is an excellent bigger darkling beetle, ranking among the easiest to rear and breed.

Adult Size - Male (15 mm), Female (21 mm)

Enclosure

E.goryi aren't particularly large or crowding sensitive, so their enclosure doesn't need to be spacious. Height should be factored into the equation if larvae are being pupated communally.

Ventilation level - 

Communal pupation (main enclosure): Very high

Isolated pupation (main enclosure): High

Isolated pupation (pupation cups): Moderate

Hides - Necessary

Barrier/Secure Lid - Not necessary

---

Substrate

E.goryi seem to appreciate sandy substrates for oviposition. The substrate should be deep (6+ inches, depending on length and width of the enclosure) if larvae are being pupated communally.

Type - 50% sand & 50% coconut fiber mix

Moisture level - 

Communal pupation (main enclosure): Top 1/3 dry, bottom 2/3 moist

Isolated pupation (main enclosure): 2/3 dry, 1/3 moist

Isolated pupation (pupation cups): Moderate

Food

E.goryi aren't picky about their food and can be fed an average darkling beetle diet.

Type - Proteinaceous pet foods, fruits, vegetables

---

Temperature

E.goryi can be kept into the low 70s, but grows and breeds fastest at warmer temperatures.

Range - 70 F to 80 F
