Northern Caddisfly (Limnephilidae) Egg Mass Northern caddisflies deposit their eggs above the water on vegetation in a 3-6 cm mass of jelly. Up to 800 eggs (the tan spots) are laid at one time in the mass! Depending on the species, the eggs can take weeks to months to hatch. These masses are usually situated so that once the eggs hatch, the larvae will simply drop down into the water, where they will spend their larval and pupal stages.<br />

    1. Thanks! I have seen these before, but would love to see them being laid and hatching! That would be amazing. Posted 9 months ago
