line-height: 30px; margin-bottom: 30px; text-align: justify\"\u003e12�日，北京落下今冬初雪，人们纷纷走上街头记录京城绝美雪景。不过，也有网友拍下稀奇的一幕——雪地上竟然有蚊子在爬行。在接近冰点的户外，为何会有蚊子？对此，成都华希昆虫博物馆馆长赵力解释，从外观特征与耐寒蚊类的分布、习性来看，这大概率是淡色库蚊或骚扰库蚊。\u003c/p\u003e\u003cp class=\"formatted\" style=\"font-size: 19px;

text-align: center\"\u003e\u003cspan class=\"img-desc\" style=\"color: rgb(127,127,127); font-size: 15px\"\u003e网友拍到北京雪地里有蚊子在爬。图片据网络\u003c/span\u003e\u003c/p\u003e\u003cp class=\"formatted\" style=\"font-size: 19px; line-height: 30px; margin-bottom: 30px; text-align: justify\"\u003e赵力介绍，从网友发布的图片来看，这种蚊子符合库蚊属的外观特征——身体呈淡褐色，喙部无白环，足上也无明显白环。而淡色库蚊是我国北方冬季常见的越冬蚊，多藏于温暖潮湿的角落，气温回升时会短暂活动，常出现在雪地周边的暖区，所以网友拍到的大概率为淡色库蚊。\u003c!--NO_AD_0--\u003e\u003c!--EOP_0--\u003e\u003c/p\u003e\u003c!--PARAGRAPH_0--\u003e\u003cp class=\"formatted\" style=\"font-size: 19px; line-height: 30px; margin-bottom: 30px; text-align: justify\"\u003e“北京地区也有骚扰库蚊活动，由于这个图片不是很清楚，所以也不排除是骚扰库蚊。”他说。骚扰库蚊抗寒能力极强，冬季可在地下恒温环境（下水道、地下室）存活，甚至无需吸血就能产卵，是城市冬季最常见的“反季蚊子”。\u003c!--AI_AD_1000--\u003e\u003c!--NO_AD_1--\u003e\u003c!--EOP_1--\u003e\u003c/p\u003e\u003c!--PARAGRAPH_1--\u003e\u003cp class=\"formatted\" style=\"font-size: 19px; line-height: 30px; margin-bottom: 30px; text-align: justify\"\u003e除此之外，环跗脉毛蚊和高山融雪蚊耐寒性也很突出，主要分布在高海拔和寒带，如北欧、我国东北山区，依赖融雪积水繁殖，是自然雪地环境中典型的耐寒蚊种。\u003c/p\u003e\u003cp class=\"formatted\" style=\"font-size: 19px;

text-align: justify\"\u003e“在北京，冬天见到蚊子在雪地上爬行，并非完全不可能。”赵力说，这主要是气候变暖、城市热岛效应以及特定蚊虫种类强大的抗寒和适应能力共同作用的结果。当冬季出现温暖的天气时，那些原本在室内或地下藏身的越冬成蚊会被“唤醒”并误判季节，外出活动。但由于外界整体气温仍然很低，它们身体僵硬、飞行困难，所以只能在雪面上挣扎爬行。冬季雪地蚊子是特定环境下的偶发现象，通常不具备威胁。做好室内环境清理，就能有效控制。\u003c!--NO_AD_2--\u003e\u003c!--EOP_2--\u003e\u003c/p\u003e\u003c!--PARAGRAPH_2--\u003e\u003cp\u003e\u003cb\u003e【如果您有新闻线索，欢迎向我们报料，一经采纳有费用酬谢。报料微信关注：ihxdsb，报料QQ：3386405712】\u003c/b\u003e\u003c!--NO_AD_3--\u003e\u003c!--EOP_3--\u003e\u003c!--NO_AD_4--\u003e\u003c!--EOP_4--\u003e\u003c/p\u003e\u003c!--PARAGRAPH_4--\u003e\u003c!--PARAGRAPH_3--\u003e\u003cstyle\u003e.rich_media_content{--news-tabel-th-night-color: #444444;--news-font-day-color: #333;--news-font-night-color: #d9d9d9;--news-bottom-distance: 22px}.rich_media_content p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:.5px;line-height:30px;margin-bottom:var(--news-bottom-distance);word-wrap:break-word}.rich_media_content .qn-editor-copy p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:unset;line-height:unset;margin-bottom:unset;word-wrap:unset}.rich_media_content{color:var(--news-font-day-color);font-size:18px}@media(prefers-color-scheme:dark){body:not([data-weui-theme=light]):not([dark-mode-disable=true]) .rich_media_content p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:.5px;line-height:30px;margin-bottom:var(--news-bottom-distance);word-wrap:break-word}body:not([data-weui-theme=light]):not([dark-mode-disable=true]) .rich_media_content .qn-editor-copy p:not([data-exeditor-arbitrary-box=image-box]):not(.qn-editor-copy){letter-spacing:unset;line-height:unset;margin-bottom:unset;word-wrap:unset}body:not([data-weui-theme=light]):not([dark-mode-disable=true]) .rich_media_content{color:var(--news-font-night-color)}}.data_color_scheme_dark .rich_media_content p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:.5px;line-height:30px;margin-bottom:var(--news-bottom-distance);word-wrap:break-word}.data_color_scheme_dark .rich_media_content .qn-editor-copy p:not([data-exeditor-arbitrary-box=image-box]){letter-spacing:unset;line-height:unset;margin-bottom:unset;word-wrap:unset}.data_color_scheme_dark .rich_media_content{color:var(--news-font-night-color)}.data_color_scheme_dark .rich_media_content{font-size:18px}.rich_media_content p[data-exeditor-arbitrary-box=image-box]{margin-bottom:11px}.rich_media_content\u003ediv:not(.qnt-video),.rich_media_content\u003esection{margin-bottom:var(--news-bottom-distance)}.rich_media_content hr{margin-bottom:var(--news-bottom-distance)}.rich_media_content .link_list{margin:0;margin-top:20px;min-height:0!important}.rich_media_content blockquote{background:#f9f9f9;border-left:6px solid #ccc;margin:1.5em 10px;padding:.5em 10px}.rich_media_content blockquote p{margin-bottom:0!important}.data_color_scheme_dark .rich_media_content blockquote{background:#323232}@media(prefers-color-scheme:dark){body:not([data-weui-theme=light]):not([dark-mode-disable=true]) .rich_media_content blockquote{background:#323232}}.rich_media_content ol[data-ex-list]{--ol-start: 1;--ol-list-style-type: decimal;list-style-type:none;counter-reset:olCounter calc(var(--ol-start,1) - 1);position:relative}.rich_media_content ol[data-ex-list]\u003eli\u003e:first-child::before{content:counter(olCounter,var(--ol-list-style-type)) '.
