Douglas fir gall midge laying eggs

Females of the gall midge (Diptera Cecidomyiidae) Contarinia pseudotsugae s.l. laying eggs between the scales or needles of douglas fir opening buds (Pseudotsuga menziesii).

After hatching, the young larvae will cause the formation of galls on the douglas fir needles.

The genus Contarinia is characterized by the long ovipositor of the females clearly visible on these images. In the last sequence, you can also see what is probably the egg passing through this ovipositor.
