Family Anthicidae (Antlike Flower Beetles)
Subfamily Notoxinae (Monoceros Beetles)
Explanation of Names
Notoxinae Stephens 1829
Numbers
>50 spp. in 3 genera in our area(1), ca. 400 spp. in 7 genera worldwide(2)
Identification
easily recognizable by the denticulate anterodorsal horn on pronotum(2) [used mainly to dig into sandy soil(1)]
Range
worldwide; most diverse in Africa(2)
Habitat
larvae usually develop in loose, sandy soils(2)
Food
adults are omnivorous, often feeding on pollen or plant exudates; cases of micropredation have also been registered(2)
Remarks
Adults (esp. males) of many species are attracted to cantharidin, a highly poisonous substance they use as a deterrent against predators (endoparasitoid braconid wasps use it to find their Notoxus hosts, too); females acquire cantharidin with male secretions they consume, and pass it to the offspring(2)
