蜇伤吃：什么都来一点

The red harvester ant is a large ant that lives in the dry, scrubby land of the southwestern United States. Its nests are dug underground, and the bare patches around them are easy to spot in open grassland. It matters because these ants gather seeds and help spread plants across the land.1

首页

Prefers dry chaparral and open, arid areas. Nests are underground, up to 2.5 m deep, in exposed ground. In grassland such as ranches, the bare mounds make colonies very easy to see.1

它吃什么？

Seeds are the main food. Workers grind them into a bread-like paste with their large mandibles and store it in a granary, so the colony has food all year. Dead insects are also collected while foraging.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

如果它蜇人

清洗并冷敷蜇伤处。
如果这个人呼吸困难、脸或喉咙肿胀，或感觉要晕倒，这是过敏急症：拨打急救电话。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它蜇了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

Some queens have been known to live up to 30 years in the wild.1

Colonies have no central control. They adjust how much they forage using feedback from returning ants, which can take only seconds.1

Rival Novomessor cockerelli ants block nest entrances with sand and small rocks, delaying the red harvester ants' activity by one to three hours.1

Seeds are stored in the nest for months, and sometimes several years, so the colony has food during lean times.1

The plants benefit too. Ants carry seeds while foraging, which spreads the plants over a wider area.1

Ant foraging is guided by chemical signals, and foragers can travel up to 50 to 60 m from the nest.1
