On 8 August 2021 I found a clutch of 14 light green shieldbug eggs on the underside of a maple leaf. After 5 days, the now cream-coloured eggs had lost their green colouring. 2 days later, life could be seen developing in the transparent egg cases. The reddish-brown spots initially documented the development of the compound eyes and ocelli of the egg case inhabitants, which took on a dark colouration before hatching. 10 days after the finding, the first small wasp hatched. After 12 days all egg cases were abandoned. The first wasp, a male, differs by its slender, evenly coloured antennae from the later hatched female wasps (last 5 segments darkened and more club-shaped). The wasps, about 1.5 mm in size, moved very quickly and lived for about 1 week.
On closer inspection of the photos, a few small, whitish, approx. 0.6 mm long eggs of unknown origin can still be seen between the shieldbug eggs (last picture).
