Size: Very Large (Wingspan up to 122mm)
Crambomorphus sinuatus is a magnificent antlion species. The head and thorax are grey and rather hairy while the abdomen is brick-red in colouration.
The forewings are mostly grey with a complex mix of black and white markings. The hindwings are black with a characteristic arrangement of white spots and blotches. The trailing edge of the wings are sinuous and end in a hooked tip.
Larvae: The larvae are very large and plain black-grey in colour.
C. sinuatus inhabits the open, arid shrublands of the Nama Karoo in flat or hilly terrain.
Adults are nocturnal and often rest in a hanging position among the protective branches of larger bushes. They are sometimes attracted to lights.
Adults are active during late summer and have been recorded from December to February.
The large blackish larvae live freely in sand and are ambush hunters. They are fearsome predators and feed mainly on other arthropods.
