34、can HomeGoliath beetles live in tropical rainforests and dry grasslands in Africa.These areas are warm year-round,with a dry season that lasts several months of the year.Wild Goliath beetles feed on fruit that grows during the wet season.While they have mouths for chewing,they also feed on tree sap,

35、which is most common during the wet seasons warm,humid conditions.Sharp claws help them scratch through bark to reach the sweet sap underneath.Goliath beetles sometimes gather on trees where food is plentiful.However,Goliaths spend most of their time on their own.“They are not social insects,”says D

36、r.Ratcliffe.Male Goliath beetles defend the best feeding sites against intruders.The heads of all male Goliaths have Y-shaped horns,which they use to push away other males.Scientists think that claiming the best feeding sites may help males attract females.Female Goliath beetles dig deep into the so

38、e and adult insects.Goliath larvae reach full size in about four months.The larger species can grow up to 5 inches(12.7 cm)in lengthabout as long as a dollar bill.They can weigh up to 3.5 ounces(100 g)about the same as five mice.ATLANTIC OCEANINDIAN OCEANAFRICAWhere Goliath Beetles LiveWhere Goliath
