Field Notes
Description:
The life cycles of insects vary but most hatch from eggs. Insect growth is constrained by the inelastic exoskeleton and development involves a series of molts. The immature stages can differ from the adults in structure, habit and habitat and can include a passive pupal stage in those groups that undergo complete metamorphosis. Insects that undergo incomplete metamorphosis lack a pupal stage and adults develop through a series of nymphal stages. The higher level relationship of the hexapoda is unclear. Fossilized insects of enormous size have been found from the Paleozoic Era, including giant dragonflies with wingspans of 55 to 70 cm (22–28 in). The most diverse insect groups appear to have coevolved with flowering plants
Habitat:
Some bees, ants, termites and some wasps are eusocial, build nest, guard eggs and provide food for offsprings fulltime (see Eusociality). Most insects, however, lead short lives as adults, and rarely interact with one another except to mate or compete for mates. A small number exhibit some form of parental care, where they will at least guard their eggs, and sometimes continue guarding their offspring until adulthood, and possibly even feeding them. Another simple form of parental care is to construct a nest (a burrow or an actual construction, either of which may be simple or complex), store provisions in it, and lay an egg upon those provisions. The adult does not contact the growing offspring, but it nonetheless does provide food. This sort of care is typical for most species of bees and various types of wasps.
Notes:
http://en.wikipedia.org/wiki/Insect --- http://en.wikipedia.org/wiki/Insect_egg --- i'm not so into beetles. i like them too, but i'm to busy with my normal work and my mycology-hobby, that i have no time/thoughts for reading some other references now. Maybe someone from you guys recognized some features for an ID suggestion.
---thanks to martinl, i have a right id, canot narrow it further in, because i didn't saw, the actually bugs. At this time, many stink bugs are out there, after looking at those eggshells, i think it could be from them.
--- After getting help into the right direction and some further research with including the common known bug here: i suspect this "hemiptera" eggshells are from some species of stinkbug (the "brown marmorated" and "green" - stinkbug are very common and numberous here).
