Buakea venusta is a butterfly ( moth ) from the family of the owl butterflies (Noctuidae).
features
The moths are small and reach a wingspan of 18 to 22 millimeters for the males and 19 to 21 millimeters for the females. The antennae are thread-like in both sexes. The color of the body ranges from whitish brown to grayish brown. The head and thorax are covered with long hair. The males are a little darker in color and have a more contrasting drawing on the forewings. There is a white line on the basal artery of the cell on the forewings. This is club-shaped at the distal edge of the cell . The veins are covered with whitish scales . Blemishes or ties are not created. The color of the forewings ranges from whitish brown in the females to gray-brown in the males. The blackish transverse band in front of the hemline forms a long, thin triangle, the base of which is near the outer edge of the wing, while the tip extends to the Cubitalader Cu2. The hind wings are whitish in the females and mixed gray in the males. A flaw is not created.
In the males, the uncus is narrow, spatulate and tapers towards the tip. On the tegumen there are small to medium-sized, rounded peniculi (brush-shaped processes). The vinculum has a well-formed saccus. The valves have a heavily sclerotized costal edge, which is divided into two at the top. Dorsally, the digitus extends beyond the cucullus, while ventrally there is a small, thick, socket-like area. The cucullus is quite thin and elongated. The juxta is almost elliptical and hardly sclerotized. When viewed from below in the dorsoventral direction, it is usually only visible as a thick sclerotized line. The aedeagus is slightly curved. The vesica has two groups of long, claw-shaped microcornuti near the tip of the penis.
In females, the corpus bursae is pear-shaped and about 1.5 times the length of the ductus bursae. There is no sign. The ductus bursae is 2/3 as wide as it is long and strongly curved at the mouth area. The ostium bursae is almost ovoid. The ductus bursae is only slightly sclerotized, mainly in the vicinity of the ostium and in its broad section. The post-vaginal plates are hardly sclerotized.
The adult caterpillars reach a length of 25 to 30 millimeters and are 3.5 millimeters thick. The head is smooth and black. The thoracic shield is yellowish brown. The body of the caterpillar is salmon-colored and shimmering. The pinnacula and the caudal plate are yellowish brown.
distribution
Buakea venusta is native to Kenya and has been found at altitudes of 636 to 1066 meters.
biology
The caterpillars live on the dog-tooth grass species Cynodon aethiopicus in open areas. The development begins with the rainy season.
