Metapelma spectabile
Westwood, 1835
Metapelma spectabile is a relatively large chalcidoid , measuring approximately six millimeters in body length—exceptional for this group of typically minute . The belongs to the Eupelmidae and is parasitic on wood-boring insects, likely targeting families such as Buprestidae and Cerambycidae. It can be encountered in the field on tree trunks with exposed dead wood, unlike most eupelmids which require rearing from .

Identification
Members of the Metapelma are distinguished from other eupelmids by their notably larger body size, approximately 6 mm, which is enormous by chalcidoid standards. The may be recognized in the field on tree trunks with exposed dead wood, whereas most other eupelmids are rarely observed without rearing. Specific diagnostic features for M. spectabile relative to are not documented in available sources.
Habitat
Tree trunks with exposed dead wood, associated with supporting wood-boring .
Distribution
Canada: Manitoba, New Brunswick, Ontario, Quebec.
Host Associations
- Buprestidae - probable wood-boring beetles
- Cerambycidae - probable wood-boring beetles
Ecological Role
of wood-boring beetles; potential agent for forest pests.
Human Relevance
May be encountered directly in the field due to its relatively large size, offering opportunities for observation without specialized rearing techniques. Holds potential for applications against wood-boring pests in forestry.
Similar Taxa
- Other EupelmidaeMost eupelmids are much smaller and require rearing from parasitized to be observed; Metapelma spectabile is distinguished by its field visibility on dead wood.
- Other Metapelma species share the large size and general association; specific separation requires detailed morphological examination not covered in available sources.
