Where D Msquites (蚊子)G in Winter?
Why d msquites , everywhere in warmer mnths, disappear cmpletely in winter? 20 Msquites are cld- blded insects, meaning that they dn't like the cld and prefer temperatures that are 80 degrees Fahrenheit r mre. When the temperature drps, they actually lse their ability t fly and becme mtinless.
21 They wuld never be able t fly far enugh. The actual answer t the questin is different fr male and female msquites. Male msquites? They die. But that's nt just because f the cld. Male msquites have far shrter lifespans(寿命)than females , and they die in autumn.
Female msquites, thugh, can live thrugh the winter. They hibernate(冬眠).In autumn, the females will g int hllw(中空的)lgs r cracks in the grund and enter this still state.22 They put ff their develpment, typically fr mnths.
When it warms up again , the females will cme ut frm hibernatin. At this pint, they're getting ready t lay their eggs and they need as much bld as pssible t help the eggs develp. The females must find a bld meal t prvide the prtein(蛋白质)needed by their eggs t develp, just in the time, when humans are utdrs in shrt sleeves enjying the warming weather. 23
It actually desn't have t be what we humans wuld cnsider “cld” t put a msquit in danger. While these pests live actively when it's arund 80 degrees Fahrenheit, mst species can start heading int hibernatin when it drps t arund 50 Fahrenheit. 24 This is when female msquites start lking fr a place fr sleep.
A. The bvius answer is that it's cld.
B. Nw it's time fr male msquites t wake up. C.It's nly the female msquites that are biting yu. D.Unlike birds, msquites dn't fly suth fr the winter. E. Anything belw 50 degrees Fahrenheit is already t cld fr mst msquites.
F. They carry n with life nly when there is enugh water fr their needs.
G.They can hibernate fr up t six mnths in freezing r waterless cnditins.
