Genus Aleeta Moulds, 2003 (Floury Bakers)

Two species (including one undescribed species) are included in this genus. It is closely allied to the genus Tryella. Representatives of both genera share the unusual habit of sitting upside down on trees. Aleeta and Tryella can be distinguished by significant differences in the overall structure of the male genitalia (Moulds, 2003).

Distribution of the genus Aleeta within Australia


Floury Baker Aleeta curvicosta (Germar, 1834)

Male

Female

TNS: 525.

Size: Forewing length: 33-51mm. Female is larger.

Range and Season: This species is distributed from Bendalong (Moulds, 1990)) on the New South Wales south coast north to near Gladstone in southern Queensland, with an isolated population in the Wet Tropics of north-eastern Queensland. It occurs in the vicinity of towns in parts of inland Queensland; however, it is not distributed far west of the Great Dividing Range. It is common in suburban Sydney and Brisbane where it is often found on ornamental trees. Adult occurrence is variable depending on location. They are mostly observed from November to May, but there are also records from as early as September and as late as June (Moulds, 1990).

Habits: Adults normally sit upside down on various types of trees and more substantial shrubs. Leafy trees are more often inhabited. Has been found on citrus in the Mundubbera-Gayndah district. Individuals are sedentary, but will scatter if disturbed. Populations occur in local aggregations.

Song: A loud hiss-like series of phrases that rapidly accelerate into a continuous hiss (shhh, shhh, shhh, shhh, shhh, shhh, shhh, shhh, shhh, shh shh shh-sh-sh-sh-sh-h-h-h-h-h-h-h-h-h-h-h-h-h...). This call is emitted during the day. At dusk a continuous hissing song is produced. The calling song spans a wide range of frequencies.

Little Floury Baker Aleeta sp. nr curvicosta

Appearance: It is usually smaller than the Floury Baker, and has a narrow opercula, but is otherwise morphologically similar.

TNS: 526.

Size: Forewing length: 31-47mm.

Range and Season: Queensland, from Mareeba south through Townsville, Clermont, Emerald, Rockhampton and Injune to the Mundubbera district and near Kandanga west of Gympie. Adults are present from October to March. Occurs along side A. curvicosta (above) in the Mundubbera district and near Kandanga.

Habits: A species of drier forests and woodlands. Around Mundubbera it is sometimes found in citrus orchards.

Song: The song has a higher dominant frequency than A. curvicosta and each sound is emitted at an even rate, with no acceleration between the short phrases and the continuous phrase (shh-shh-shh-shh-shh-shh-sh-h-h-h-h-h-h-h-h-h-h-h-h-h-h-h-h shh-shh-shh-shh-shh-shh-shh-shh-sh-h-h-h-h-h-h-h-h-h-h-h-h-h...) etc.
