Speckled longhorn

Speckled longhorn

Pachytodes cerambyciformis

A species of Pachytodes

Adorned with an intricate pattern reminiscent of light and shadow dappled on tree bark, speckled longhorn boasts an elongate body and antennae, the latter often spanning longer than the insect's own frame. With a life cycle that metamorphoses from wood-boring larvae to nectar-sipping adults, this species intricately links the wellbeing of forest ecosystems to its own, contributing to nutrient cycling as they navigate through both arboreal and herbaceous landscapes.

Habitat Preferences of Speckled longhorn Through Different Life Stages
The larval stage of speckled longhorn typically inhabits the inner wood of various deciduous trees, particularly favoring weakened or recently dead timber. Seeking them requires careful examination of the bark and potential boreholes. Pupation occurs within these wooden substrates, meaning a search would involve the same types of locations. Adults, however, are often found on or near the flowers and foliage of their host trees during the warmer months, using visual cues and gentle inspections to avoid harming the insects or the plants.

Larva Larvae of speckled longhorn are wood-borers, typically found in dead or dying hardwood trees or logs. Search for them by looking for boreholes or sawdust-like frass on or around infested wood.
Pupal Speckled longhorn pupae are typically located inside the wood where the larva has been feeding. Locating them requires carefully dissecting infested wood.
Adult Adult speckled longhorn can be found on or around host trees. Look for them on warm days when they are most active, often near flowers or on tree trunks.
