Population Up! Good news from Mexico. Monarch population is up dramatically from record lows of past 3 years. |
Time to Celebrate! Inspired by the monarch population rebound, people are celebrating the good news and continuing with conservation efforts. |

Severe Storm Strikes A winter storm of historic proportions has struck the monarch sanctuaries in Mexico. |
Impact of Storm Reports reveal great destruction from last week's storm, but the impact — on the monarchs and their habitat — remains unclear. |
Migration Underway! Here come the monarchs! Get ready to track spring migration. |
Crossing Texas Laying eggs as they travel, northbound butterflies are delivering the next generation. |
Building in Texas Survivors of the storm are now arriving in Texas, having traveled 700 miles on tattered wings. |
Final Flights Faded monarchs in their final flights are striving urgently to reproduce. |
Following Milkweed With milkweed paving the way, the leading edge of the migration is now 1,300 miles from Mexico. |
Nearing the End No longer their brilliant orange, the monarchs from Mexico are nearing the end — and a new generation is about to continue the journey north. |
New Generation A new generation is emerging and a surge in sightings is about to occur. |
Waiting for Surge Monarch enemies take a big bite of a monarch's potential offspring, so how does a population grow? |
Few and Far Between As monarchs migrate north, watch out for imposters. How can you tell this is not a monarch? |
Here They Come! Riding a river of wind, the monarchs advanced 250 miles northward this week all the way to latitude 45°N in Minnesota. |
Sightings Soar The migration exploded across the northern breeding grounds, with 36% of the season's first sightings reported in a single week. |
Nearing Northern Limit With migration almost complete, the milkweed patch is the place to be. Females are looking for milkweed and males are looking for females. |
Expanding Eastward From 10 acres of winter habitat, monarchs have now expanded across 1 billion acres of breeding habitat. How many generations will they produce where you live? |
Peak Breeding Season The population builds with each new generation and will reach its peak when fall migration begins in August. |
