Phymateus aegrotus, the East African Bush Locusts, is a locust in the family Pyrgomorphidae.
Distribution
This species is present in Africa, Northeast Tropical Africa, Somalia.[1][2]
Description
Phymateus aegrotus can reach a length of 80–100 millimetres (3.1–3.9 in) in males, of 60–80 millimetres (2.4–3.1 in) in females.[3] Body is green in colour, while fore-wings are blackish and yellowish. The nymphs (hoppers) in the first instars are mostly black with several small yellowish markings, while in the last instar they are bright green.
Biology
These locusts lay eggs in the substrate (humus-sand mix), The eggs hatch after about 12 months. The life expectancy of adult animals is of 8–12 months.[3] They are capable of long migratory flights.
As with other Phymateus species it raises and rustles its wings when disturbed and may secrete a noxious fluid from its thoracic joint.[4]
The East African Bush Locusts feeds on bramble, Asclepias, bittersweet nightshade, Cestrum nocturnum.[3]
