It’s back to school time, which for me means gathering friends and family to help me collect antlions. This will be my 6th year using antlions, thanks to Brad Williamson.<\/p>\n

It really is a fantastic way to start the year. Students see a boring pit of sand in a cup, until the inevitable accidental bump and they realize, “It moves!” We first practice generating questions, then students will design a short investigation. Much more information can be found in Brad’s post:\u00a0Ant Lions and Biology<\/a>.\u00a0\u00a0I recently heard Paul Anderson talking about the Question Formulation Technique on the Horizontal Transfer Podcast<\/a>. I’m pretty sure Brad had us do this technique in Research Methods. I will be trying it this year with my kids.<\/p>\n

Many teachers I talk to about this have a lot of questions\u00a0about collecting and sorting them. I thought I’d share some tips and tricks as I’m preparing for the first day of biology class.<\/p>\n

Collecting<\/em><\/p>\n

Antlions are readily available in Kansas, but sometimes they’re hard to find when you’re actually looking for them. They love fine loose dirt or sandy substrate and some kind of protection overhead. I always find them around houses that have an overhang, or under porches where bare soft soil is found. I also see them in my parent\u2019s pasture near trees or under the cow feeders.<\/p>\n

The best tools I\u2019ve found to capture the antlions is a metal spoon. The antlions mandibles can usually be seen at the very bottom of the pit.<\/p>\n

Knowing the location of the antlion within the substrate, scoop with the spoon under the pit. If disturbed, they will back up and are sometimes hard to find. My method is to go through and scoop the pits, and put all the scoops into the same bucket. I sort out individuals later, because it’s easier and I don\u2019t always get an antlion with every scoop.<\/p>\n

Sorting and Preparation <\/em><\/p>\n

I use 2 oz cups, which work well for one antlion each. \u00a0If you get substrate from outside, or if you have substrate with large pieces, you could sift it before adding it to the cups. Fill the cups with substrate and have them ready.<\/p>\n

One spoonful at a time, look for the antlions. Sometimes they are difficult to see if they don\u2019t move. I shake the container, or blow on the substrate and wait for movement. Put one antlion each of the prepared cups.<\/p>\n

DO NOT DISCARD THE DIRT THE FIRST TIME YOU GO THROUGH IT! I guarantee there will be antlions that you miss. Every 7-8\u00a0scoops, I put into a pie plate. I leave these pie plates out overnight. The next day, you can see pits or \u201cdoodles\u201d to find the antlions.<\/p>\n

At the end, I even put all the dirt I\u2019ve gone through into one final container and wait to see if there are any pits. There usually are!<\/p>\n

Now I have individual containers ready for the students. While the antlions sometimes make a pit within an hour, they all should make one overnight.<\/p>\n
