Damselflies Laying Eggs

damselfly laying eggs2 354The two damselflies in this photograph have mated, but the male is still clasping the back of the female‚Äôs head so as to guard her and prevent her from receiving the sperm of another male before she is through laying eggs. Damselflies lay their eggs both in the water as well as in plants. The pictured female (bottom damselfly) is in the act of using her ovipositor (thin black structure at tip of abdomen) to puncture a cattail leaf and insert her 1 mm- long egg into the plant tissue. If you look closely, you will see holes in the leaf blade above the hole she’s currently making, where she has previously laid eggs. Thousands of these holes may be drilled and eggs inserted into them during her brief life.
