FIELD SCHOOL!

Entomology is a component of field school; it can be extremely exciting to find "good bugs", especially after a hearty chase! On a more scientific note, insects caught during field school have been noteworthy in that they have represented extensions of known ranges, or have become specimens retained by our collection, and that of the NS Museum of Natural History.

Here are some examples:

 

* Syneta extorris borealis (Chrysomelidae)
* Necrobia violacea (Cleridae)

Necrobia violacea (Linné) is an introduced Palearctic checkered beetle. There are records from Halifax, Kings, & Cape Breton County but this is only the fourth [Nova Scotia] locality (and first on the northern shore). Most clerids are found either as predators of bark beetles in coniferous forests or else on flowers but this genus specializes in carrion where they saprophagous and predaceous of fly larvae. They are neat, pretty, and not often collected.


Graphoderus liberus (Dytiscidae)

Graphoderus liberus (Say) is not that unusual: there are records from Antigonish, Halifax, Lunenburg, & Kings counties but it seems to be not often collected (I've never found it, but then I don't do a lot of collecting of aquatic Coleoptera). We do have 3-4 specimens in the collection but it is a nice addition.

* Pterostichus pennsylvanicus (Carabidae)
* Hydroporus striola (Dytiscidae)

Hydroporus striola (Gyllenhal) is broadly distributed in NS and not uncommon but we only have one specimen of it in the NS Museum collection, so its a good addition to the collection.


* Quedius molochinus (Staphylinidae)
 

Quedius molochinus (Gravenhorst) is previously recorded only from Kings & Queens counties. It may well also be more widely distributed but Staphylinids are (despite their huge numbers) less collected than many other species of beetles so for many species distribution records are spare. There isn't a prior specimen in the NS Museum collection.


* Tropisternus mixtus (Hydrophilidae)
* Dineutus nigrior (Gyrinidae)
