Then came the Dutch in 1641, followed by the British, who made their move in Penang in 1786.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">All that empire-building reshaped entire ecosystems.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cThey cleared rainforests to grow cash crops like coffee, rubber, and coconuts,\u201d Ruizhi says. \u201cThat created new environments and new food sources for insects.\u201d<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The colonial officers were benefiting greatly from this (financially, of course), but there was a problem \u2014 insects started eating up the \u201ccash crops\u201d.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Cue panic from colonial officers. The very insects they weren\u2019t bothered about (or unwillingly transported across oceans) began feasting on these money-making crops.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Colonial administrators documented their battles with bugs, thus leaving behind a pile of historical records.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cTheir anxiety became our archives,\u201d Ruizhi says. \u201cThey wrote a lot of reports, letters, notes, and that\u2019s what I study.
