Indiscriminate Cuckoo Bumble Bee (Bombus insularis)


Overview

Overview

Indiscriminate Cuckoo Bumble Bee (Bombus insularis), a Wisconsin State Special Concern bee is found in a variety of habitats rangewide. As of 2018, Wisconsin has only three observation records, which were from Iron (1953) and Outagamie (2009) Counties. Rangewide, it is found in the northern tier of states in the eastern U.S. and in the mountains in the western U.S. Wisconsin's three observation records took place between June and August. Rangewide queens emerge in May and enter diapause in August.

State status

Status and Natural Heritage Inventory documented occurrences in Wisconsin

The table below provides information about the protected status - both state and federal - and the rank (S and G Ranks) for Indiscriminate Cuckoo Bumble Bee (Bombus insularis). See the Working List Key for more information about abbreviations. Counties shaded blue have documented occurrences for this species in the Wisconsin Natural Heritage Inventory database. The map is provided as a general reference of where occurrences of this species meet NHI data standards and is not meant as a comprehensive map of all observations.

Note: Species recently added to the NHI Working List may temporarily have blank occurrence maps.


Documented locations of Bombus insularis in the Natural Heritage Inventory Database as of July 2015.

Landscape-Community combinations of highest ecological priority*

Ecological priorities are the combinations of natural communities and ecological landscapes that provide Wisconsin's best opportunities to conserve important habitats for a given Species of Greatest Conservation Need. The 10 highest scoring combinations are considered ecological priorities and are listed below. More than 10 combinations are listed if multiple combinations tied for 10th place. For more information, please see the Wildlife Action Plan.

* Ecological priority score is a relative measure that is not meant for comparison between species. This score does not consider socio-economical factors that may dictate protection and/or management priorities differently than those determined solely by ecological analysis. Further, a low ecological priority score does not imply that management or preservation should not occur on a site if there are important reasons for doing so locally.

Issues/threats and conservation actions

Conservation actions respond to issues or threats, which adversely affect species of greatest conservation need (SGCN) or their habitats. Besides actions such as restoring wetlands or planting resilient tree species in northern communities, research, surveys and monitoring are also among conservation actions described in the WWAP because lack of information can threaten our ability to successfully preserve and care for natural resources.
