Elm Leafminer
A sawfly whose larvae mine between the upper and lower surfaces of elm leaves. Mines appear as blotchy brown patches on foliage.
Did You Know?
Each larva creates a single blotch mine that can expand to cover half the leaf.
Arctic Parasitic Wasp
A slender parasitic wasp with a black body, orange legs, and long antennae. Females search for caterpillar hosts on tundra vegetation. The larva develops inside the host caterpillar, eventually killing it.
Did You Know?
This wasp has been extensively studied as a model for understanding host-parasitoid population dynamics in changing Arctic ecosystems.
