Calvert – Ladybug Larvae and Pupae

Hello Garden Friends,

Last Friday at Calvert was the last day with the second graders. We took a few minutes to reflect on all the good times. Singing “roots, stems, leaves,”… learning about warm and cold veggies, bees, and greenhouse gases… planting starts and sowing seeds.. so many good memories. The lesson focused on how the earth provides and talked about all of the things that plants give us (other than food and air). They give us shelter, fire, clothing, paper, colorful paint, seasonal decorations, and medicine!

To demonstrate how plants can be used to make dyes I chopped up a head of purple cabbage and had the students massage the leaves into a solution of water. The cabbage released its purple pigments into the water and we ended the lesson with an acid and base magic show. When I added vinegar the cabbage turned pink; with baking soda – blue.

While saying goodbye to the garden we stopped by the arugula plants and saw so many hungry ladybug larvae! Check the featured image for an example. Below you see the next stage of development called a pupa, or plural pupae. After the pupa is the adult stage where the ladybugs are less hungry and focus more on reproduction.
